Thanks for your bug report. I believe there is a newer version of the kernel available for Feisty. Could you please update your kernel and report back on the results? Thanks in advance.

It seems that the kernel is not finding your '/' (root) partition. Do you happen to know what it is? If so you could manually edit the kernel boot line and change root to '/dev/sda99' or whatever is appropriate to get it to boot. After getting it to boot you will then want to use 'vol_id /dev/sda99' to determine the right UUID for your '/' (root) partition. Then modify your '/boot/grub/menu.lst' and '/etc/fstab' appropriately.

Should be fixed in 2.6.20-12.

[X-pLoSioN (tobiasburg)]

[X-pLoSioN (tobiasburg)]

no problems with starting with 2.6.20-13!
