Out of interest, what systems are you seeing mismatches on? Most of the
ones I've seen are on LSI1068* SAS controllers (with SATA drives, but
not sure if that counts for anything, don't use many SAS drives)
including the Dell SAS5* and SAS6* series. I suspect there are some
corner cases where they corrupt data on disk. Should open a kernel.org
bug really, so that LSI can ignore the issue in public...
Tim.
