:> I just built the world and a new kernel on one of my DELL2550's and
:> the same problem happens. This is a stock 2550, there's no chance
:> of the SCSI backplane being broken and it worked fine with an older
:> kernel.
:>
:>I've included two boot verbose dumps. The first is with the latest kernel.
:>The second is with the previous (working) kernel.

The patch appears to have fixed the problem! Thanks!
I will also run some heavy disk I/O tests overnight.
