I apologize if this has been covered, but do these changes or the ones made a
month ago fix the issues people have been having with the mvsas driver on 64xx
based cards like my AOC-SASLP-MV8 (based on a MV64460/64461/64462 Rev B)?

I have a relatively recent 2.6.38 kernel running the box with the mvsas
controller (with 7 SATA drives). I've noticed it doesn't panic when plugging
in a drive which is nice, but I don't have the courage to attempt a hot
unplug. I am still getting a significant number of device reset and libata
invalid sector 0 errors.

Example of such errors:

[394488.800081] /build/buildd-linux-2.6_2.6.38-4-amd64-eEW_ml/linux-2.6-2.6.38/debian/build/source_amd64_none/drivers/scsi/mvsas/mv_sas.c 1632:mvs_query_task:rc= 5
[394491.008046] /build/buildd-linux-2.6_2.6.38-4-amd64-eEW_ml/linux-2.6-2.6.38/debian/build/source_amd64_none/drivers/scsi/mvsas/mv_sas.c 1586:mvs_I_T_nexus_reset for device[3]:rc= 0
[394491.008070] ata12: translated ATA stat/err 0x01/04 to SCSI SK/ASC/ASCQ 0xb/00/00
[394491.008519] ata12.00: device reported invalid CHS sector 0
[394491.008526] ata12: status=0x01 { Error }
[394491.008532] ata12: error=0x04 { DriveStatusError }

I get at least 10 of those a day. (it is better than it was)

Thanks.
