Hello all,
On Feb 29 my Fedora 16 box updated itself (I'm not wild about the only
options being completely manual update or completely automatic update -
but that's another story). It must have updated the Kernel because the
next day when I turned on the PC I had a kernel panic (details below)
and the machine failed to boot.
I had a zero timeout on grub so this meant that I had to use a Mint
liveCD to edit grub so that I could try booting with the previous
kernel.
The fact that I am able to write this shows that the previous kernel on
the very same machine boots without problem. This is the "previous"
working kernel:
$ uname -a
Linux localhost.localdomain 3.2.6-3.fc16.i686.PAE #1 SMP Mon Feb 13 20:44:23 UTC 2012 i686 i686 i386 GNU/Linux
The kernel that is failing is 3.2.7-1.fc16.i686.PAE
Below I have tried to type as accurately as possible the kernel panic
message that I get when I try to boot into the new kernel (note It's
typed manually - NOT copied and pasted - so i might have made the odd
typo).
What should I do?
I can think of no obvious hardware problem given the fact this the
machine boots happily with the previous kernel...
Thanks in advance...
Mark

Looks like either dracut didn't put the driver you need for your hard
drive in the ramdisk image or the grub configuration is telling it to
use the wrong root partition. Check the grub config first and make sure
the entry for the faulty kernel has the same root partition as the
working kernel.
