Hi,

I've been trying to get an AOC-SASLP-MV8 card (pcie x4 2 port SAS card) to
work with linux for the past month or so. I've recently just RMAed my first
card, and tested the new one under linux, and I see the same problems.

The very first time I made a new array off the controller, formated (with
 xfs) and mounted the volume, it seemed to work. ioozone even seemed to run
 for a while. Sadly after a few minutes I got a stream of mvs_abort_task
 messages in dmesg, and any accesses to the volume, or any disks connected
 to the controller lock up.

After that I updated my 2.6.31 kernel to 2.6.32-rc3-git2 off of kernel.org,
and the volume fails to mount with the same mvs_abort_task messages.

I've attached my dmesg log from both attempts. dmesg1 is the first attempt,
dmesg2 is the second attempt on the newer kernel.

I would really appreciate some help with this.

I should also mention that if I attempt to remove any of the drives while the 
card is in a hung state, the entire machine locks up with the keyboard LEDs 
blinking.

This does seem to be a rather serious error.

If there is more I can do to help track down the problems, please let me know. 
I really need to get this to work (my current array is FULL, and may be 
showing signs of failure) as soon as possible.

I can pretty much wipe and reinstall everything at any point on this machine, 
update/install new kernels, etc. I just don't have a null modem cable atm to 
hook up a serial console to capture the errors on OOPSes.

Thanks.
