[Bug 576302] [NEW] regression: root device not found (mptspi)

[Anton Gyllenberg]

Public bug reported:

After upgrading from Karmic to Lucid, my old Dell Poweredge no longer boots, but fails with:
Gave up waiting for root device. [...]
Alert! /dev/disk/by-uuid/... does not exist. Dropping to a shell!

I can boot 2.6.31-21-generic, but with 2.6.32-21-generic and
2.6.32-22-generic I get the error. I recall I got the error earlier as
well but it resolved itself by rebooting I think. Now this consistently
works with 2.6.31-21 and fails with 2.6.32-21 and -22.

Waiting and exiting, or setting rootdelay=120 doesn't help. The device
is not found, /dev/sda1 never appears. The end of the kernel output
looks like the following. This is hand copied by typing while looking at
the screen so there may be errors:

scsi2 : ioc0: LSI53C1030 B2, FwRev=01011800h, Ports=1, MaxQ=222, IRQ=25

I'll attach lspci and dmesg output after booting 2.6.31-21-generic that
works.
