Public bug reported:

First encountered in CR Bug #270118 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/270118 for 8.0.4 32 bit
Turns out that this is an arbitrary problem. The only thing that saved me from a complete boot fail was the UUID disk string in grub. 

The fstab entries were looking for a sda and sdb device while during this boot they were renamed to sdc sdd.
This time the problem recurred for 64bit
Linux owl 2.6.24-23-generic #1 SMP Mon Jan 26 01:04:16 UTC 2009 x86_64 GNU/Linux

Looks like inserting a SD MMC card in my Dell 2408WFP results in
renumbering - the SDMMC becomes sda while the HDD becomes sdc. Possibly
might occur only when Bios detect for USB HDD is enabled - I will post
update about this after reboot check with bios feature disabled.

Attaching dmesg and dmesg.0 showing that disks have been renamed.

My guess is the kernel scsi driver code needs fixing.


PS: I generated this with the ubuntu-bug cmd, but don't see any info
attached. Let me know if you need more info.
