Custom kernel SuperBlock error Please Help!!
Hello,
I have Arch linux installed on a virtual machine for a class project where we are required to hack the kernel. I have successfully modified the linux kernel 2.6.28 code, compiled and booted with the custom kernel. This morning I made the last final changes to the code, recompiled, but when I boot I am greeted with:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
The Arch kernel boots fine however. There were no errors during kernel compilation. Any thoughts/suggestions.
Thanks for the reply, yes this is after grub and no it is not ext2, it is ext3. I ran into this problem on another virtual machine after several kernel builds so I did a fresh install of Arch and the kernel build (along with booting the new kernel) was fine.
Note this:
The last time I compiled my kernel (virtual machine 1) I did rm -rf * on /usr/src, copied my kernel stuff into /usr/src and did the compile got the ext2 error, however, the Arch kernel was fine.
On the second virtual machine, I was in a major hurry so I copied my kernel stuff into /usr/src compiled, everything was fine. Went back into the code, made some changes recompiled got the ext2 error the Arch kernel again was fine.
I realized on these last two builds, I didn't create the symlinks
# ln -s /usr/src/linux-2.6.28 /usr/src/linux
# ln -s /usr/src/linux-2.6.28 /usr/src/linux-2.6
Could this mistake be the cause??

Windows - No Disk Error - Please help!
Hi,
I have the following set up:
* Lenovo T-61p
* Windows XP Pro, SP 3
* HP Photosmart 8250 printer (with nothing plugged into the various card readers, and USB slot in the printer)
I am getting the following error:
Windows - No Disk
Exception Processing Message 0xc0000013 Parameters 0x75CE023C
0x84C40C84 0x75CE023C
I have done a lof experimenting and thru process of elimination, and believe I have determined that this only happens when the HP Photosmart 8250 printer is plugged in to the USB slot of the computer.
I can stop it from happening by safely removing hardware, and removing the drive that the 8250 creates on your computer when you plug it in. In my case, this is drive E. I'm guessing if there was something in the the various card readers, and USB slot in the printer, that's what those would be, but I don't those use those functions of the printer.
I understand there is more at work than simply the printer, because I did not used to get this error, so some software changed as well, that is scanning all ports, and finding a drive that has no disk, and producing the error.
A simple google search finds a lot people all over the world having this problem, and are solving it in different ways, because the suspected source is different: Norton, HP, etc.
I have tried everything I have read, and the only thing that works was my own idea, of manually safely removing the drive the printer creates each time I plug in the printer.
Anyone every any better, more permanent solutions? Or know what the real root of the problem is? What is scanning all the drives and being showing an error message because it found an empty drive?
Thanks and Happy Holidays/New Year!I've been getting the same error on my 4G nano for the past week. I've had my nano for about a month and the first few weeks were fine. Tried it on 2 different computers (Vista and XP) and same problem. Tried it on a 3rd (XP) and it started ok. Problem started coming back after a day.
I was able to find a quick fix though. I noticed that sometimes the message says something like "iexplore.exe... no disk..." even if I don't even use IE. What I do is end iexplore.exe on task manager before running iTunes and syncing my nano. I don't get the error whenever I do this, but one drawback is that the contents of my nano suddenly pops up in a window - even when disk use is not enabled.
I've reset/restored my nano dozens and dozens of times to make sure it's clean. Leads me to believe it's a driver issue. Either that or I have a friggin malware problem I can't seem to find.
I'll be posting updates every now and then. I'm no expert so I'm hoping an Apple expert also steps in to give some input. -

Hey erinoneill24,
Thanks for using Apple Support Communities.
Sounds like you can't update your device. You don't mention an error that it gives you. Take a look at both of these articles to troubleshoot.
iPod displays "Use iTunes to restore" message
http://support.apple.com/kb/ts1441?viewlocale=it_it
If you can't update or restore your iOS device
http://support.apple.com/kb/HT1808?viewlocale=de_DE_1
If you started your device in recovery mode by mistake, restart it to exit recovery mode. Or you can just wait—after 15 minutes the device will exit recovery mode by itself.
Have a nice day,

frobtarget with the correct class path specified. The 6.0 JAAS sample is
trying to invoke on examples.security.acl.Frobable, make sure this is the
deployed instance. This is an error in the JAAS example SampleAction.java

this bug will be corrected in service pack 1 which will be available
shortly.

Update Server
Try:
- Powering off and then back on your router.
- iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
- Change the DNS to either Google's or Open DNS servers
Public DNS — Google Developers
OpenDNS IP Addresses
- For one user uninstalling/reinstalling iTunes resolved the problem
- Try on another computer/network
- Wait if it is an Apple problem
Otherwise what server are you talking about -
