Comment 31 for bug 32123

1)My platform is amd64.
I've upgraded from Gutsy to Hardy beta.
After the rebooting my computer hung up on """Begin: Waiting for root file system... ..."""
I pressed "reset" and booted old kernel 2.6.22-14, then i run "sudo
update-initramfs -k all -u"
as a result the problem was fixed(2.6.24 now working fine).

2)Investigation:
I decompress two file initrd.img-2.6.24-12-generic and initrd.img-2.6.24-12-generic.bak.

The following difference was disclosed:

*** bak 2008-03-23 16:25:21.000000000 +0300
