F9 kernel 220.127.116.11-18 update broke grub.conf
Last modified: 2008-06-02 10:44:20 EDT
Description of problem:
When updating the newly-upgraded (F8->F9) Fedora 9 system (kernel 2.6.25-14)
with 'yum update' in my dual-boot (Win XP & Fedora) x86_64 desktop box to kernel
18.104.22.168-18 and rebooting, the boot process stopped at a stage where only the
word "GRUB" was displayed on screen and the system loudspeaker kept on playing
'error' sounds. Ctrl-Alt-Del was able to stop that and reboot, but I never got
past the "GRUB" stage. Neither of the OS'es could be booted.
Version-Release number of selected component (if applicable):
I don't know. What is the anaconda version on the F9 DVD?
Hard to say. This may be a hardware-specific problem or the result of upgrade
instead of clean install. It has happened to one other reporter on fedora-list
Steps to Reproduce:
1. Upgrade F8->F9 on an x86_64 platform
2. Update kernel from 2.6.25-14 to 22.214.171.124-18
Booting stops at "GRUB" and rings system loudspeaker
Boot continues to a fully operational F9 system
I used the F9 DVD and its "Rescue" option. Checking grub.conf revealed that
(probably) anaconda had rewritten grub.conf to contain lines such as:
kernel /vmlinuz-126.96.36.199-18.fc9.x86_64 ro
root=UUID=ab562fb5-0a9a-4458-9f30-61c8a23f774a rhgb quiet
instead of the expected:
kernel /vmlinuz-188.8.131.52-18.fc9.x86_64 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
I replaced the "UUID=..." with "/dev/VolGroup00/LogVol00" using vi and rebooted.
Now both OS's *can* be booted but I wonder why my UUID ended up in grub.conf. I
can't figure out how it could be useful to GRUB.
I forgot to mention that *before* editing grub.conf I ran grub-install. I'm not
absolutely sure whether I tried rebooting after running grub-install but I
probably did - to no avail. However, after editing grub.conf and rebooting,
everything seemed to be OK.
