James, 2.6.28-rc1 introduced a bug about scsi lib. We reported it at http://bugzilla.kernel.org/show_bug.cgi?id=11898. Patch at http://bugzilla.kernel.org/show_bug.cgi?id=11898#c36 already fixes the bug. But 2.6.28-rc6 has no the patch. Although there is a performance issue, could you push the patch to upstream firstly? It seems the performance issue isn't related to the patch.
