Highly likely, as it was seagate disks I had this issue with. The comment
in the hptmv driver:-
+ /*
+ * always use 48bit LBA if drive supports it.
+ * Some Seagate drives report error if you use a 28-bit command
+ * to access sector 0xfffffff.
+ */

You must be very careful with using less than 48bit addressing when
both
the drive and the controller supports it as some disks report errors
at
none standard crossover points.
I saw this first hand with the highpoint driver where it totally
trashed
the RAID volumes. The solution was to "always" use 48bit addressing if
the drive supports / requires it.
Could this be the thing that is at stake ?
The mirror, consisting out of ad4/ad6 got its ad4 trashed with the
patch enabled. luckily it could be rebuild from the intact ad6.
