Thanks for the help from Steve Fox and Duane Cox investigating this issue, I'd like to report that we found the problem. The issue is with the patch Steve Fox isolated below, by not accommodating older adapters properly and issuing a command they do not support when retrieving storage parameters about the arrays. This simple patch resolves the problem (and more accurately mimics the logic of the original code before the patch). ObligatoryDisclaimer: Please accept my condolences regarding Outlook's handling of patches. This attached patch is against current scsi-misc-2.6 and can apply to 2.6.21-rc6-mm1. Please consider it for expedited inclusion.

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. -- Steve Fox IBM Linux Technology Center
