[Bug 549568] Re: ubuntu x86_64 upgrade 2.6.31-21 fails to show x logon screen but 2.6.31-20 works fine

[Bob Felstead]

Hi all,

I'm having issues with the latest release of Kernel 2.6.31-21 on a 32bit
system. after installing the update, the system wouldn't boot into X, I
simply got the sh:grub> prompt. After some time at the command line I
did manage to get the sytem to boot using the follwing commands, -

ismod ntfs
set root=(hd0,1)
loopback loop0 /ubuntu/disks/root.disk
set root=(loop0)
linux /boot/vmlinuz-2.6.31-14-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro
initrd /bootinitrd.img-2.6.31-14-generic
boot

Then I rebuilt grub2 and re-booted the system -viola problem resolved.
HOWEVER, I still can't boot into  kernel 2.6.31-21 as the system hangs,
-

[0.969559] kernel panic - not syncing:VFS:unable to mount root fs on
unknown block (8,1)

Any ideas? I know that I'm not the only one with this issue.

Bob
