Description Bob Agel 2007-03-04 12:32:23 EST
Description of problem: This kernel results in a Kernel Panic for me.  Here's
the kernel selection from /boot/grub/grub.conf:

title Fedora Core (2.6.19-1.2911.6.4.fc6)
        root (hd0,3)
        kernel /boot/vmlinuz-2.6.19-1.2911.6.4.fc6 ro root=LABEL=/ rhgb quiet
/dev/hdb1
        initrd /boot/initrd-2.6.19-1.2911.6.4.fc6.img

In fact, FC6 is on hda5, not on hdb1, which is actually the T-2 for Fedora7. 
Removing rhgb quiet and /dev/hdb1 results in the same kernel panic.  Here's the
lines leading up to it:

mkroot: expected fs options
mount: missing mount point
setting up new root fs
setuproot: moving /dev failed no such file or directory
no fstab.sys, mounting internal defaults
setuproot: error mounting /proce: no such file or directory
setuproot: error mounting /sys: no such file or directory
switching to new root and running init.
unmounting old /dev
unmounting old /proc
unmounting old /sys
switchroot: mount failed: no such file or directory
kernel panic - not syncing: attempted to kill init!


Version-Release number of selected component (if applicable):
kernel 2.6.19-1.2911.6.4.fc6

How reproducible:
every attempt to boot

Additional info: kernel 2.6.19-1.2911.fc6 and prior kernels all work fine

(typo - FC6 is on hda4, not hda5.  Sorry for the fumble fingers)

Here is a screenshot of my panicing kernel:

Try "root=/dev/hda4". You might also have to edit /etc/fstab
and change everything in there to point to the right filesystems.

In general multiple Fedora installs will cause problems because they
all think they own the label "/".

Well, it's fixed but the fault was mine to start out with.  I had problems with
Fedora7-T1 and mounted it in fstab to make the correction, however I did not
correct fstab once the problem was solved.  That's where the 'hdb1' was found.

Unfortunately, simply removing the fstab entry did not correct the problem and I
had to remove and then reinstall the problem kernels and kmods.  Once
reinstalled, all works perfectly.
