Comment 27 for bug 358054

I have this problem as well, and as the above poster commented, I do not have any md array partitions. (The drives might have been a RAID at one point, but they were cleaned and grub was reinstalled) I upgraded from 8.10 to 9.10... via a quick stop at 9.04. The bug appeared in 9.04 and only by booting an old kernel 2.6.27-14-server was I able to scrape-along and get the machine up.

My boot drives are on the motherboard and are identified as sde and sdf. The software raid a.k.a. "fake RAID" card handles my storrage array of 4 drives... listed as sda through sdd. If it is worth mentioning, all drives are IDE and not SATA... so somewhat confused as to why the BIOS presents them to ubuntu as "s" drives in unix. (I would have thought they would have been "h" drives?)

The problem seems to be kernel related, but maybe the auto-upgrade messed up/confused grub? I vaguely remeber having to tell it to boot from hd(x:y) where x. y weren't the standard 0,0.
