After kernel update system dont boots

i updated my kernel, update process was ok but now when i try to boot my system i got these types of errors in middle of the booting:
ERROR: Failed to parse device name for '/dev/disk/by-uuid/[many symbols which i didnt copied]
it looks like it cant find root, but it found it before update, please help because i dont wanna reinstall system.

EVRAMP wrote:Try to edit grub boot menu: instead of "/dev/disk/by-uuid/[many symbols which you didnt copied]" write your root partition path "/dev/sda2" (where sda2 points to your root partition).
You can edit your grub boot menu entry by presing "e".
didnt help, i tried that at first. now when i booted ubuntu from live cd to look whats inside arch linux partition, i went to /dev/ and ive seen only three files, no sda* or somethink, just three empty text files. i tried to look at this folder as a root, but still theres only three files. so maybe theres problem? man i will need to reinstall everythink again :(

  • Automatically build kernel module after kernel update

    Hello. Everytime kernel is updated, my wifi drivers don't work. I need to use this to get my adapter working: https://aur.archlinux.org/packages/8192cu-dkms/ .
    After kernel update, I have to manually reinstall the package, so the kernel module gets rebuilt. Is there any way to make it automatic?

    I noticed it, but your script doesn't run at all when I type `mkinitcpio -p linux`. And wifi still works after reboot. Same for graphics driver, it has a hook at shutdown, that rebuilds its module after kernel update, it haven't run too and graphics driver works. It's like 'mkinitcpio -p linux' does nothing to the system.

  • Automatic recompiling of kernel module after kernel update.

    Hello everyone,
    i tried to search for it but without success...
    my question is - is it possible to set it up somehow that aur package would recompile after kernel update?
    The package I would like to rebuild is rt3090 which is module for my wifi card. It is very annoying to rebuild it manually. I know that my fglrx module does it automaticaly but how to set it?
    Thank all of you for any advise.

    Thank you :-) It looks ok, I will try DKMS as soon as I get some free time. If there was any problem, I would tell you.
    BTW: I use catalyst mainly because of saving energy management, which is of course better for my netbook. My card is too new to be fully supported by the opensource driver.
    EDIT:
    I solved the situation by upgrading my system, I tried in-kernel module rt2800pci. In the previous kernels it didn't work well with my crappy ralink rt3090 wifi card, but that's been improved :-) so I do not need rebuild the package anymore even because this module isn't compatible with newest kernel.
    I also learnt how to write my own hook from archwiki (https://wiki.archlinux.org/index.php/Mkinitcpio) so if the new module didn't work I would try it.
    The final solution = replace module rt3090sta by rt2800pci.
    Thanks! Arch has very powerful community :-)

  • VMware player won't start after kernel update

    Hi,
    today I've updated to 3.9.6-1 kernel and all went good. So I wanted to start my vmware player to start a vm. Of course I've done the needed steps in the vmplayer wiki page to setup the new headers and stuff after kernel update for vmplayer. Also I've ran "vmware-patch -f" and ran trough. But still get an error when I wanted to start the player in the "/tmp/vmware-root/vmware-modconfig-11986.log":

    Maybe it has something to do with the last filesystem update?
    But I don't know what to do really and couldn't found anything on that.
    thanks

    sorry, found something now in another thread here. this fix works just fyi:

  • [Solved] Can not build modules for VMware Player after kernel updates

    I have a problem generating the modules for VMware Player after kernel updates. I am using  VMware Player version 5.02 (without patches) and the softlink according to the Wiki.
    When I start the installation of the modules from the GUI, the program just closes. Running vmware-modconfig in the CLI generates the following log file:

    Interestingly, after deinstallation and reinstallation the VMWare Player works fine.
    Any hint, what's going wrong?

    Today, (Kernel  3.10.5-1, VMware Player version 5.02 with kernel patches) the modules could successful be generated from the CLI:
    vmware-modconfig --console --install-all
    Solved (somehow).

  • Lost network after kernel update

    Hi
    I have lost my network after kernel updating the kernel [2.6.35.7]
    I downgraded to kernel 2.6.35.6

    Hi,
    I'm just reporting that I had this issue today too. I rebooted my computer from Win7 to Arch64 and I was left without network. Also it doesn't work in windows after rebooting back. I thought that It is something with connection so I tried to recoonect cable and also tryied to swap it in switch/adsl gateway. It started working after several switches (not on 1st!) It looks like interface is repeating on and off. So I rebooted to Arch and it stops working again...
    I fixed it by reinstalling kernel26 package. But it is strange because it works yesterday, last thing what I did with kernel and modules was update of gc nvidia drivers... I don't know when I updated kernel last time
    I'm using same network driver as Karol - r8169
    lsmod | less
    mii                     3826  1 r8169
    I'm using this card as well.  I upgraded yesterday and I can't get wireless with WICD.  Windows and normal network daemon work fine.  I use kernel26.  What other info can I provide?  If a bug report needs to be filed, would it be WICD, kernel26 or other?
    Also, I forgot, but I'm not using normal Wicd, I'm using wicd-nogtk from AUR.  Krychle, are you using this also?
    Edit:  I think this has to do with the python update.  I updated wicd-nogtk and its good now.  I am online.

  • After kernel update, anything i should do for my arch system in vbox

    Hi all:
    I've installed arch as a vbox guest system. The host system is windows 7.
    After Archlinux kernel updates, do i need to re-install the guest add-on modules ?
    or is there anything necessary after each kernel update ?
    Best Regards,

    Thanks for the reply.
    I've already installed the virtualbox-archlinux-additions.
    So after the kernel update there's nothing i need to do ?

  • Module 'asus-nb-wmi' stopped being auto-loaded after kernel update

    Well, the module 'asus-nb-wmi' which takes care of some FN keys and keyboard backlight stopped being auto-loaded after the latest kernel udpate (3.9.3), so I had to add it to /etc/modules-load.d/ to get it working. This has happened before, between kernel updates and I had to re-install arch to fix it, but now I found that manually adding the module is a nice solution, but I want it to be loaded automatically or at least know why does this happen. Kernel modules, such as this one, should be loaded automatically right?
    Best regards.
    Last edited by DanielRS (2013-07-04 19:54:48)

    I think there is a valid question here;  Same thing happened to me.
    Upon a default install of arch, the module was auto-loaded without the user touching any configuration files
    at some point during kernel updates, the module is no longer auto-loaded
    the user then has to find out what is happening and go add the module to the appropriate config file to force load on boot.
    So the larger question is; without config files being taken into consideration, how does the kernel decide what modules to load?  f
    I know it has something to do with the hardware that it detects, but am unaware if this is something within the RC or systemctl booting system, or if this is part of the kernel.
    I'm going to dig around some more on the internet, as i'm sure the answer is out there somewhere.. but if someone that is on this forum happens to read and know the answer, it would be nice to know
    thanks

  • Mounting issues after kernel update (2.6.25)

    After installing the recent kernel update, mounting has gone haywire. When I put in a cd (in either of my 2 drives) it doesn't mount. In thunar, when I click on the cd drive, it displays this error:
    mount: wrong fs type, bad option, bad superblock on /dev/sr0,
           missing codepage or other error
           In some cases useful info is found in syslog - try
           dmesg | tail  or so.
    I did dmesg | tail and I got this:

    Also, when booting a few minutes ago, it was stuck on the "checking filesystems" for a few minutes, when it usually does that step almost immediately. I also couldn't mount an iso, this is what happened:
    [root@eric-arch eric]# mount -o loop -t iso9660 /path/to/iso.iso /mnt/iso2
    mount: could not find any device /dev/loop#
    Note: I am not certain that it was caused by the kernel update, but that is the only thing I did to my machine before this started happening.
    Please help asap because I need to do schoolwork which is on a cd.

    jealma wrote:I know the solution to the /dev/loop-problem. The new 2.6.25 kernel has the loop device as a module. Please try a `modprobe loop`, that gives you a /dev/loop. I don't know whether that will be persistent after a reboot, so you may need to add "loop" to the modules-list in /etc/rc.conf.
    That worked, but I still have other issues with cd mounting, so I downgraded my kernel for now.

  • Wireless issues after kernel update

    Hi,
    after I updated my kernel yesterday, I've been having some issues with my wireless. I'm on a dell inspiron 1545, using kde and I use the broadcom-wl driver form the AUR.
    Anyways. After I did a system update yesterday, it would refuse to load the wl module. So I recompiled the driver and that was fine. But still my laptop refuses to use its wireless card. At first I just couldn't connect to any wireless, now the networkmanager just claims that my WLAN Interface is unavailable.
    the output of iwconfig:
    lo no wireless extensions.
    eth0 IEEE 802.11bg ESSID:"" Nickname:""

    but if I try to run 'iwlist eth0 scan' it states:
    eth0 Failed to read scan data : Invalid argument
    I'm not that experienced with wireless, so I did what https://wiki.archlinux.org/index.php/Broadcom_BCM43XX says and some other pages I found on google. 'iwconfig eth0 up' doesn't have any influence.
    As I said, before the upgrade it worked fine and I also had configured it as it is described in the link above.
    thanks for any inputs,

  • [Solved] Overheating/fan/sensors issues after kernel updates

    Hi all,
    I realise there has been a bit of correspondence on this already.  I'm after some advice for my specific situation:
    1. My laptop is an acer aspire 5315.  I has well understood overheating issues that arrise due to BIOS problems
    2. Fan control and temperature reporting worked perfectly with kernel 2.6.30, stopped working with 2.6.31 - I assume due to the well documented changes made in that release.  The temperature only seems to be read once - at boot.  sensors never reports a change after that; if the temperature is cold at boot the fan never get switched on.  Unfortunately this happens most often.
    3. I tried setting the recommended kernel option (can't relocate the post now).  It didn't help :-?
    4. I have tried upgrading the BIOS but the distribution from acer is a windows executable (won't run under freeDOS) and I do not have windows installed on this PC (not game to try under wine).
    5. I re-installed the old kernel from my pacman cache only to find that my wireless no longer works (fan works just fine though).
    I'm now totally stumped :-/
    I'd like to update my bios and go with the latest kernel but can't see a way without installing windows.
    This might be fixed in an ubuntu kernel release (https://bugs.launchpad.net/ubuntu/+sour … bug/453700) but I'd prefer not to do that switch... perhaps the same fix is coming to arch?
    I'd accept having to pin the kernel to an earlier version but neet to get the wireless working.
    help...
    edit: 
    I've now managed to get the kernel backdated correctly (so that wireless works as well as the fan) by re-installing the kernel and firmware together.
    Have configured pacman to igmore future kernel updates
    If anyone has any suggestions on howto update my bios I'd be very greatful.

    Hi,
    Got exactly the same issue, after running for a while laptop justs goes off... going to try to regress kernel until issue is resolved
    BIOS update does sound a bit extreme

    fstab originally existed on my OS before the pacman upgrade. After the upgrade I got the error message mentioned above (and obviously the fstab was there since I  didn't touch it). Then after reading that linked topic (where a similar error message was the cause of systems not booting due to a fstab), I deleted the fstab (or more accurately, moved it somewhere else)

  • [Solved] Nvidia after kernel update

    The nvidia wiki clearly states that: "Every time the kernel26 package is updated, it is a requirement to reinstall the nvidia package and rebooting afterwards. "
    But my question is, why? I mean, if the module was to be recompiled, that would make sense. But what does just reinstalling the driver accomplish? In my system, pacman -Ql nvidia shows:
    $ pacman -Ql nvidia
    nvidia /etc/
    nvidia /etc/modprobe.d/
    nvidia /etc/modprobe.d/nouveau_blacklist.conf
    nvidia /lib/
    nvidia /lib/modules/
    nvidia /lib/modules/2.6.35-ARCH/
    nvidia /lib/modules/2.6.35-ARCH/kernel/
    nvidia /lib/modules/2.6.35-ARCH/kernel/drivers/
    nvidia /lib/modules/2.6.35-ARCH/kernel/drivers/video/
    nvidia /lib/modules/2.6.35-ARCH/kernel/drivers/video/nvidia.ko
    From what I've read, I think the kernel update process copies the compiled modules into the proper folder (inside /lib) named by the kernel version. Should this not be the case with nvidia? If it is not, then is this why the reinstall is needed?
    Thanks in advance (and my apologies if I've glossed over something that's patently obvious --- while I've searched for the answer before posting, I am still quite the novice at tinkering with the kernel)
    EDIT: just after posting I've realized that maybe this post belongs in "Kernel and Hardware Issues" subforum. But the truth is this isn't really an "issue"... it's more a question from, well, a newbie :-)

    Thank you for the feedback.
    ngoonee wrote:Of course, if you're using nvidia-beta or some other AUR nvidia driver, you need to reinstall it.
    Running the risk of asking what might be obvious to some, why?
    The driver speaks to the kernel. When the kernel updates, the language used might have changed in various ways. Since nvidia is closed-source, its not always obvious whether what has changed affects it. The same applies to xorg-server, when it updates you should recompile your nvidia driver. Its SOMETIMES not needed, but when it is, would you rather be solving it from the tty?

    ngoonee wrote:That's what the wiki is referring to. Even if the kernel major version has not updated (for example 2.6.35.5 to 2.6.35.6 is only a minor version bump) the driver may need to be recompiled. Safer to just do it everytime and restart the machine.
    Now I'm confused. Are you saying that the safest approach is to recompile and (re)install the nvidia module after each kernel update? And does this only apply to modules from beta & AUR, or [extra] as well? And shouldn't all this issue of recompiling modules also apply to every other module installed in the system?
    Yes that's the safest approach. [extra] is taken care of by the devs, the simple way is to assume they'll bump it if needed (and you don't need to do anything).
    The same thing applies to almost any kernel module (AFAIK). It applies to virtualbox's modules, for sure, as well as phc-intel (the only other 2 external modules I use). Most kernel modules are actually compiled in to the kernel26 package anyway, so its not very many. I just automatically recompile the ones I use whenever I notice a kernel/xorg update.

  • Broadcom-wl-dkms not reinstalled after kernel update

    I use broadcom-wl-dkms for my wireless card (Broadcom BCM4352 rev 03). All works well, until the kernel is updated.
    I expected dkms to rebuild the package automatically, but apparently something goes wrong in the process: after every one of the last few kernel updates, the module was correctly rebuilt on reboot, but not re-installed.

    Apart from telling me that the broadcom-wl install failed, I don't see much in there.
    Any clue on what's going on? Thanks!

    The open source driver might work or might not. For me it was extremely unreliable and slow. Use the broadcom-wl driver or b43 like ugjk suggests.The wl driver is in aur.
