Subject: mvsas errors in 2.6.36

Good news and bad news, the current mvsas driver in 2.6.36 seems to work
better than older kernels with my setup (2 port sas + 5 SATA disks). But I
gotten the following messages so far:

I did not unplug a disk, the errors seem to be spurious.

Otherwise though things seem to be working. At least so far. The mv_abort_task
part is very familiar, the older version of this driver would do it right
after attempting to build/activate the md raid5 array that lives on this
controller. Except the controller would lock up, and all drives would become
inaccessible.

I'm going to attempt to grow this array today, so long as the xfs_fsr that I
started doesn't cause the array to fail.

If I keep getting mv_abort_task errors, I'll have to back down to the copy of
the driver I got from Andy Yan. I've managed to patch it up to compile for
2.6.36 just now, I just hope it'll work at least as well as it did with
2.6.34. At the very least I didn't get these errors.

Some background, the disks attached to the card are (5) Seagate 7200.12 1TB
disks, using SAS->SATA cables. Machine is a amd64 Phenom II X4 810 w/4G
ram running debian sid and a vanila 2.6.36 kernel. The card is a
AOC-SASLP-MV8, according to lspci:

I just hope the raid5 reshape I'm about to do doesn't crap its pants because
of the errors above.

I'd like to help test any fixes or changes if needed. Let me know.

Thanks again.
