Kernel panic during or immediately after startup

We have an ibook G4 running tiger (can't get to see which version now as I can't get beyond the login page). Nothing has changed today as far as I know, but my partner was using it, not me.
He first got a kernel panic message (the 'you need to restart your computer' box) when trying to use airport, then when he restarted the message turned up part way through start up.
I've done the PRAM reset procedure at the beginning of start up, which helped the first time, but after another hour or so use, the restart message popped up again, and after that restart, the kernel panic message appeared at the login page.
Any suggestions gratefully received.

  • Kernel panic on first boot after 10.6.8 update

    Hi,
    Here are the fact:
    1) I systematically get a kernel panic on first boot after an attempt to update to 10.6.8 (was able to revert to 10.6.7 using Time Machine; now I'm running my tests on a clone). While doing the update, there are NO USB connexion to my laptop, nor ethernet connexion. Only the power cable.
    2) I DO NOT use the software Hands Off which is known to cause such an issue
    3) I've tested this on two different hard drive (with a clone of my system)
    4) I disabled all third app on startup just to be sure this wasn't a conflict problem
    5) After a kernel panic, I'm always able to boot in safe mode
    6) I did try both the normal update and the combo update (same result)
    Now I'm kinda stuck. The next test I'm thinking performing is to update while in safe mode. But I don't know if it will help.
    And yes, my permissions are all fine. Any idea how to troubleshoot this? I believe I need to be in 10.6.8 in order to update to Lion?
    Many thanks in advance!

    Hi,
    Sorry about that. Below you'll find the log of my latest kernel panic.
    I did follow instructions suggested by user "ds store". The only "kext" file that I've got (by running the commands in the Terminal) was related to the software LittleSnitch. I downloaded it again in order to run the uninstaller. I'll try again to update to 10.6.8 under those conditions and report here.

  • Kernel panic during Leopard 10.5.3/4 net-installation

    Hi,
    We have built universal Leopard images on net-install server. I am getting kernel panic during net-installation of 10.5.3 and 10.5.4 images on old iMac bubble G4 machines. These images's net-installation works perfect on latest machines like G5, Intel MacPro, iMac G5.
    I am not getting any problem with 10.5.2 image with this old bubble machine. But this problem occurs only after 10.5.3 images. Here is a small part panic trace, (Sorry, I couldn't get full trace since there was no way to copy it)

    Any help will be appreciated.
    Thanks,

    Hi Rohit;
    It appears your Leopard question has been posted in the OS 9 forum. You might have a better chance for an answer if you report over in the Leopard forum.

  • Why do I get a kernel panic during large downloads?

    Since I got my new MacBook Pro, it's been doing kernel panics during large file downloads.
    Getting rid of Chrome seemed to help but today the panics are back.  I just started up in Safe Boot mode and the downloads (two files, approx. 500 and 300 MB, respectively) completed downloading without incident.
    While I'm checking out my startup items, has anyone else seen this problem?  I didn't have this problem with my Core 2 Duo.

    I took a look at the dump and saw a reference to an Elmedia Player kext.  I remembered that in another thread someone mentioned this giving some trouble, I uninstalled it.  I'll keep an eye on it to see if the problem comes back.
    Here's what I've got:

  • Adobe CC products either closes almost immediately after Startup or closes after giving the message "Could not validate license"

    Okay, so I recently got all the products I wanted from CC via the student subscription. It was a bit of a pain getting everything working, as windows explorer crashed and reopened during installation of CC and during an update. Once I finally got in and got everything installed, I thought I was golden, it was then that I discovered my troubles had only just begun. Whenever I tried to open a program it either closed almost immediately after Startup or closed after giving the message "Could not validate license". Thus far I have not found a solution, as the much touted log out and log in method failed me.
    Any help in this area would be greatly appreciated as I am honestly at a loss on what to do.
    Technical details:
    The programs I tried were After Effects, Audition, Photoshop and Premiere.
    I am using Windows 7.

  • Frequent kernel panic during boot up

    Hi,
    I am having frequent kernel panic during system bootup. It takes atleast 3-5 attempts for the machine to boot-up without a panic. It is not consistent. I have disabled dropbox and removed firefox and chrome which I suspected was causing the problem.
    Any idea what could be causing the panic? Once the system boots up, it some times stays up for a long time before a panic happens again.
    The error report is below. Let me know what other details are required to trouble shoot this issue.

    Thanks for the pointers and suggestions. The system was up and running with out any panics. So I decided to upgrade to Mountain Lion. I was able to download it through App Store and start the installation. Everything went through fine and finally when it had to restart, it took a long time and stopped at the grey screen showing the prohibitory sign.
    After waiting for quite a long time decided to hard restart the machine. Same issue. So used the option keys at bootup and went into disk utility.
    Verify disk permission threw up some errors. Then Verify Disk started throwing up errors and stopped in between and suggested to run Repair Disk.
    When I ran the Repair Disk it threw up an error mid way and said:
    Error: Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restor your backed-up files.
    I ran Repair Disk again and it went through fine. No issues this time. Ran fix permission option as well. That also went through fine. Then restarted the system.
    No use - It still shows the prohibitory sign and progress circle....just stays there....
    Any advice on what next?
    Thanks,
    Sudhir

        Hi Hallry,
    Let's free your device! It's important to have a properly working device. Have you attempted an alternate Hard Reset on the device http://vz.to/19r2DOO? If the alternate Hard Reset does not work, then the device would need to be replaced. How long have you had this device? Any liquid or physical damage to the device? Keep me posted

  • Kernel panics during TM backup

    I have been having problems with kernel panics during Time Machine backups and I would like to find out if others have had similar experiences. If this is a problem unique to my configuration, then I need to do more work. If others are having the same issue, then perhaps I just need to wait until a fix is issued.
    Some background, I am using TM on two computers, an early 2006 iMac and a first generation Aluminum 15" Powerbook. On the iMac, TM is now very reliable, on the PB, it will ALWAYS kernel panic at least once during a large backup, sometimes 2 or 3 times before it manages to finish the backup. Since I have been playing around with backup disk configurations, I've made several initial backups, so I've also seen quite a few kernel panics, but ONLY when TM is running a large backup.
    Are you hit with kernel panics during TM backups? I see some discussion along those lines in this forum.
    The most recent initial backup was with Spotlight disabled and it DIDN'T panic. This was unusual. As TM is adding files to the backup disk, Spotlight is busy indexing the new files at the same time. It is possible that the two are not playing well together on the lower performance machines, such as this 1.25 GHz G4. By adding the backup disk to Spotlight's privacy list, Spotlight is inhibited from indexing the backup disk.

    For information, this problem appears to be due to some unique problem with my particular computer.
    I had been having 2 or 3 kernel panics every day. Finally, I did a Safe Boot and the panics ceased completely. Not one in the last month. Looks like it was some kind of corrupt data that the Safe Boot cleaned up.

  • Kernel Panic during Installation

    Recently, Tiger (in my macbook) has been experiencing crazy problems. Programs refuse to start, quit suddenly, the OS X get kernel panics, and other issues. So I went to the this Apple message board and ask. I tried various solutions; they all work, BUT the problems would return and new ones arise. The main solution was reparing disk and its permissions. It worked at first but troubles persist. So then I decided to reinstall Tiger through archive and install. It almost finished but once it was setting up iwork, everything stopped for an hour until I manually shut the computer down. I attempted another try, same problem. So I moved onto erase and install. Everything worked out well until I came to the setup info screen. Things were going fine until BAM, kernel panic. I shut down the mac again and it loads os x. Now i'm afraid things will repeat itself. How often would one get a kernel panic during installation (in this case info setup)? I just want everything normal.
    Mac mini, MacBook   Mac OS X (10.4.7)   1GB, 1.25GB Ram (respectively)

    How often
    would one get a kernel panic during installation (in
    this case info setup)?
    Um...never? Kernel Panics are never something you should encounter on any sort of regular basis. Sounds like it could be a bad hardware component, most likely the RAM. Has it been upgraded since you got it?
    Anyway, I'd take it to an Apple Store or get on the line with AppleCare asap.

    can any one help me out here, tomorrow I am going to boot it into target disk mode and install from a G5 onto the powerbooks HD doing a CLEAN install and then I am going to try booting it from a DVD and doing another CLEAN intstall just cause I dont trust a firewire install for some reason. I would like to avoid all this mess if possible. ANY HELP PLEASE, either respond or email me tend0 at mac dot com. thanks

    haha oh man thanks for startin slow with me, but we are passed that tested RAM, start up items, prefs, tried makin a new user account, as I stated before I can not boot from a DVD/CD.. that was one of the problems so I cant run anything that involves tageting the main HDD while its mounted. I have also repaired perms, ran fsck, tried booting up DiskWarrior(didnt boot from the CD), etc. if any one knows this perticular kernel panic string and can point out what the conflict is I can resolve it but other than that I have ran the run of the mill check to see if everything is in order procedure again and again.

  • Kernel Panics during startups - cannot boot anymore

    First: Sorry for my bad english - i hope you still can understand...
    The facts:
    - MacBook 2,0Ghz - 2gb Ram.
    - After 8 weeks --> random shutdowns. In OSX, in Bootcamp, in any application, even during booting OSX
    - Replacement of the logic board, after suggested by AppleCare
    - After that: OSX instable. Totally. Safari, DVD Player, Firefox, Adium.... any application crashed almost every 5 minutes
    - Even sometimes: Kernel Panics. One time even at the login screen
    --> I tried a reinstall --> Archive & Install
    - DURING the installation of DVD 2 --> Kernel Panic.
    - Sucessfully installed OSX in the second try
    - OSX seems to run fine - I do the update to .7 trough SoftwareUpdate
    - During reboot --> Kernel Panic.
    - and now: during EVERY reboot (short after the apple on grey background) a Kernel Panic. I took a picture of that:
    http://tinyurl.co/jon89
    And now? I am sad! Crying! I don't know what to do anymore.. I'm writing now in Bootcamp-Windows - this is still running...
    ANY suggestions?
    sniff,

    Hi, Hauldhagen. Welcome to the Discussions.
    See my "Resolving Kernel Panics" FAQ. This FAQ includes step-by-step instructions for identifying and resolving some of the most common causes of kernel panics.
    My FAQ is a roadmap: start at the beginning and work through to the end, following the instruction in the order specified, including the "If all else fails..." section if a cause or resolution is not found in an earlier troubleshooting step therein.
    Good luck!

  • Logging Kernel Panic during startup.

    Occasionally I have Kernel Panic while the Loading Modules stage. Can I redirect the error to a file (it is quiet large)? I don;t have a serial port to connect a terminal.

    I've been trying to find some way to capture panic info without a serial port, too. The best thing I came up with was kdb/kgdb. It will page through the panic and stack dump, and let you look at the kernel log buffer in memory. I just looked, and I think it's running at that point in the bootstrap.
    kdump/kexec might be another possibility, but I don't know about loading a panic handler that early..
    If you find anything, post back. I'm interested, too.

  • Kernel Panics during system boot, and no kind of network connectivity

    I've tried quite a lot of things here, so please read them all before you suggest something - and thanks for taking a look at my question (-:
    I recently got my Mac Pro back from the AlaskaMacStore (not an actual apple retail store, and they aren't very good at that), having brought it in for loss of FW800. They sent it to Apple, and I received it back, supposedly with a new motherboard - and my FW800 working. However, it proceeded to kernel panic (complete visual system freeze, not greyscreenofdeath - oddly enough, iTunes would never stop playing during them) at least once a day after that.
    Not wanting to deal with them again, I just used it like that and put up with it - but soon enough, I lost any sort of network connectivity as well. With AirPort connected to my Time Capsule's network (which worked fine on my Macbook Air and iPhone and various other devices), I was being told "...Self-Assigned IP address, and thus may not be able to connect to the internet...". Even connected directly via Ethernet to the Time Capsule, or directly via Ethernet to the cable modem, or directly via Ethernet to another Mac, or connected to another Mac's ad-hoc network, I could get absolutely no network communication going on of any sort.
    This was too much for me, as all of my work requires frequent and heavy internet access, so I gave in and took it back to the local mac store equivalent - they charged me 100$, and kept it two days, just to tell me they 'couldn't reproduce the problem'. I took the Mac Pro to a friend's house, and went through the same tests - connected to his modem, with his Ethernet cords, and to his wireless and other macs. Same deal, no connection or indication of a networking being connected beyond that blasted 'self-assigned IP' in Network prefs.
    Having no desire to be defrauded by the local fools again, I decided I didn't really have anything important on my internal hard drive, and decided to wipe the internals and re-install Leopard. My horrible luck continuing, I found my only Leopard disc to be cracked, prompting me to drive out and purchase a new one. Inserting this into my Mac Pro's drive, I found myself faced with yet another horrible problem.
    During the boot to the Leopard DVD, the grey loading screen (with the apple logo and the spinner) simply froze with the spinner pointing left. I left it for a while, expecting this to be part of what I'd previously experienced with the slow boot-from-DVD on a Macintosh... but after 30 minutes of waiting, I got quite worried, and booted back into my normal OS by holding down Option and selecting my RAID.
    Now, note this for later - it booted absolutely fine, and though I still had no network connectivity, the system had no problems. I changed the startup-disk to my RAID and then back to the Leopard DVD, naïvely thinking this would solve the problem, and ran into the same problem after restarting and booting to the Leopard DVD again.
    Dismissing this as a optical drive problem (haven't had occasion to use optical media in nearly 3 years, don't really trust it in general), I booted the Mac Pro into Firewire Target Disk mode, and connected it to my Macbook Pro, and then booted the Macbook Pro from the installation DVD. Again, note carefully here - there was nothing wrong with the DVD itself, as the Macbook Pro had no trouble booting to the DVD.
    I used Disk Utility to preform some planned modifications to the internal drives of my Mac Pro (erasing my previous inefficient RAID setup in favor of a new, faster (but less secure) RAID0 striped setup for my main two 1TB drives), and then proceeded to install a fresh Leopard onto the newly minted RAID. I usually cancel the 'disc checksum' that the Leopard DVD runs on itself, not really worrying about it, but in light of recent possible problems with the DVD, I went ahead and let it run - no problems, it completed and went straight into the normal install.
    The install itself completed in a timely manner, and my Macbook Pro re-booted automatically, to the newly Leopard-ed RAIDed internals on the Mac Pro. It booted to the new install without a hitch, played the Leopard intro video, and continued to the setup cube. I opted to shut down (by hitting command-q and selecting the shut down option), so I could set it up on the Mac Pro instead.
    Surprised was I, when I experienced the same grey loading screen freeze on the Mac Pro, booting to the newly clean install on the new RAID, that I had seen trying to boot to the Leopard disc. Worrying that my Leopard disc was, infact, corrupted in some way, I tried placing the Macbook Pro into firewire Target Disc Mode, and booting that drive over FW800 on the Mac Pro. Same freezing problem occurred.
    Well, now, the only installation that HADN'T kernel panicked on boot was the old install, and that had been erased for the new RAID configuration, so I was left without a way to boot to a working install and test things from the Term. This left me with Single User Mode, which I immediately booted into.
    Interestingly enough, there was no problem booting into Single User Mode - so I poked around a bit before mounting, and I had seemingly fine access to the entire filesystem of the new Leopard install, and nothing looked screwed up to my (albiet untrained) eye. After mounting and continuing the boot, it froze - but since this was verbose SUM, and not simple normal boot, I was able to see exactly where it froze: something about 'mDNSResponder starting', and then no input or output was accepted, leaving me assuming it had kernel panicked again.
    To test this, I again attempted to boot from the Leopard DVD on the Mac Pro, this time in verbose startup mode, and watched it freeze up at exactly the same point. After a little googling, I found some suggestions to disable the launchd plist for mDNSResponder - I tried SUM again, and did so, then continued with the boot. This time, there was no output relating to mDNSResponder, so the launchd change had worked; however, it still froze - this time, right after three lines, first something along the lines of 'Login Window Application Starting', and then two lines printing Ethernet IDs of some sort. After those Ethernet related lines, it again froze.
    What with the DNS and Ethernet bits showing up in the freezing, I was getting worried this was still tied into my NIC in some way, so I unplugged my Ethernet cords and tried the exact same boot again, and again disabled mDNSResponder. This time the only sensible thing before the freeze was the 'Login Window Application Starting' line, which seemed perfectly normal. I doubt there is/was anything wrong with that, so I'm assuming there's still some networking-related process freezing/panicking the computer, and it just doesn't happen to log in a visible way during startup.
    Does anybody have any suggestion as to what such a process might be, and how I can at least pause or kill it from SUM, so I can at least finish booting the computer?
    If I can't figure out a solution to this, I'll have to buy a new Mac Pro tomorrow morning... I have very, very pressing matters that can't wait for a new Mac Pro to ship, nor can they wait for me to ship this one to Apple and back (I live in Alaska, we have at least a weeks wait if nothing is seriously wrong when sending an Apple product in for repairs on our own), and nor can I wait 2 days for the local Apple store to tell me there's nothing wrong with it and then have to wait another week to, again, send it to Apple myself. I don't want to have to shell out for a new, expensive computer when there's a (most likely) perfectly good one sitting here... so any help would be MUCH appreciated.
    If you've read this far, phew, you deserve a cookie. That was one... long... post.
    (If you care, this post was cross-posted to my blog, at http://blog.elliottcable.name/posts/macpro_epicfail.xhtml)

    Talk about bad luck.
    The point at which the system "freezes" with the gray spinner (and just after the login window app starts) is right about the point the accelerated drivers should kick in for the video card.
    So a couple things could be going on.
    1) bad video card dragging down the bus
    2) The system board is fubar - this I think is likely - issues with onboard ethernet, and whats seems to be video card related.
    I would hazard to guess that the PCI-express bus has something wrong with it, ethernet and video live on the bus, SATA, and USB live in the southbridge.
    So, looks like a trip to a certified apple dealer/repair center is next for your Mac Pro - probably for a new system board, again?
    Something tells me that your system really didn't get to Apple for a new board.
    You can verify by looking at the serial ID tag on the system board, note the rev and serial # before and after such repairs.
