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 have the exact same problem with another Marvell 88SE64xx based card,
namely an Areca ARC-1300ix-16 and the mvsas driver.
If the disks are just used alone, with a filesystem on them, all seems
to work fine. dd and badblocks run fine on them. Mounting them,
reading/writing work fine. The error seem to popup but rarely when
several disks are used simultaneously.
But, an absolute sure way to trigger the error is to assemble (or
create) a md raid array with the disks. I join a syslog extract from the
error. You can see it happens seconds after the array creation.
I tried :
1) disabling the write cache on the disks => same error
2) disabling NCQ : in mv_sas.h :
#define MV_DISABLE_NCQ 1
same error.
Afer a while, the devices handled by the card are just dropped from the
system and the card stops working at all, a reboot is necessary.
Does anyone have a working config based on a Marvell 64xx card ?
I'm willing to explore solutions, patches or anything, just tell me what
to do to help.
Christian Vilhelm.
