Since 2.6.21-rc5-mm1, one of the test.kernel.org machines (elm3b239) has
not been able to boot because it cannot find the SCSI device. You can
view http://test.kernel.org/abat/82623/debug/console.log for the latest
boot log (rc6-mm1).

I tracked this down to the git-scsi-misc patch in the -mm tree and then
bisected the scsi-misc git tree until I reached the commit below from
Mark Salyzyn:

fe76df4235986cfacc2d3b71cef7c42bc1a6dd6c

[SCSI] aacraid: Fix blocking issue with container probing function (cast update)

This is a pretty big patch, so hopefully Mark can take a look at it.
lspci shows

01:02.0 RAID bus controller: Adaptec AAC-RAID (rev 02)
0f:02.0 SCSI storage controller: Adaptec AIC-9410W SAS (Razor ASIC
non-RAID) (rev 08)
1d:02.0 SCSI storage controller: Adaptec AIC-9410W SAS (Razor ASIC
non-RAID) (rev 08)
2b:02.0 SCSI storage controller: Adaptec AIC-9410W SAS (Razor ASIC
non-RAID) (rev 08)

on 2.6.21-rc6. Let me know if I can provide more details.
