I'm not too familiar with how all of this works (libata, libsas,
sata-over-sas, etc), but I'm happy to do any debugging necessary here
-- the machine is not yet in production. Based on what you said, this
sounds like a mvsas/libsas/not-libata issue, right? The reason I sent
the report here was that libata-core.c was involved. I guess
linux-scsi would be the better recipient of this then?
