:>    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.
