Default Fedora 16 kernel panic

Hello Fedora Users list!
I sent this recently to our local LUG list, but no one was able to help. I looked to see if this has been talked about and as far as I know, it hasn't (outside of something similar with Fedora 15, but it seemed the solution there was incomplete).


I have 3 kernels installed on my Fedora 16 laptop --*kernel-3.2.2-1.fc16.i686,*kernel-3.2.5-3.fc16.i686 and*kernel-3.2.6-3.fc16.i686. When I try to boot 3.2.5-3 or 3.2.6-3, I get a kernel panic message with the message "initramfs unpacking failed uncompression error" followed by "not syncing, no init found". Both of these were installed via normal yum updating; nothing out of the ordinary for them.


In the beginning, booting into the oldest one, 3.2.2-1 has no problems, fortunately. Haven't seen anything helpful mentioned on the Interwebz about such an error, was wondering if anyone had seen something similar. Just to be sure, I removed the 2 newer kernels and then did a "yum install kernel" to see if something was corrupted the first time, but I'm still getting the same results.*


The last time I reboot, *all* of the kernels would give the error message. I was able to first boot into single-user and then, when exiting, it boot properly. I just installed the latest kernel update and (3.2.7.x) and getting the same thing.


Thanks!
Brian

Brian,



What does your grub or grub2 config file look like?

It is just a gzipped cpio archive, try running it through
gzip -d < initramfsfile | cpio -t (or something like that,
I'd check the options if I were you :-).

If that fails, the file is probably corrupted.

So 3.2.2 isn't booting now either (at least, not until single-user
mode and then exit)?* Have you tried updating dracut and then
rebuilding your initramfs with dracut -f?

Default Fedora 16 kernel panic

Thank you all for the responses. I went to reboot my laptop into the old 3.2.2 kernel to confirm that it was having the same issue, and it boot into it with no problem. I then reboot my laptop and let it start up with the latest 3.2.7 kernel, and it, too, started with no problem again.


There doesn't seem to be any consistency to it. Hadn't had a chance to make any of the suggested changes below....

One possible explanation is dodgy memory: do give it a check. The
memtest86 on a Fedora install would be good for that. There’s also a
chance that some other part of your system (possibly the processor)
isn’t working quite properly: keep an eye out for that. (One traditional
stress-test for processor and memory is a kernel compile).

Hope this helps,

James.

Hmm, yes, that is interesting. It boots into the newest kernel now with no changes from you when it wasn't before. Definitely sounds
like it could be hardware related.
