Would just like to chime in with a "me too" on this. I've tried both ubuntu
9.10 kernel (2.6.31) and their 10.04 pre-alpha (guess it's 2.6.32-rc8) and
mvsas + AOC-SASLP-MV8 is pretty much unusable. If I start md creation it
stalls immediately and gets nowhere, last time I tried it md claimed it had
written 160 blocks then it stalled (all drive LEDs on the controller is
constantly lit).
If I boot without drives and then hot-plug the drives, it immediately
oops:es.
Any code/fixes I can try, this is a lab machine so I can easily do whatever
needed with it...
Hi,
I had a bit of trouble finding some patches that were released by Andy Yan at
Marvell on November 9th, so here is a link:
1/7: http://kerneltrap.org/mailarchive/linux-scsi/2009/11/9/6558753
They applied cleanly to the ubuntu 10.04 2.6.32 kernel source package but
when compiling I received an error about "sas_change_queue_depth" having
wrong amount of arguments:
- sas_change_queue_depth(sdev, MVS_QUEUE_SIZE);
+ sas_change_queue_depth(sdev, MVS_QUEUE_SIZE, SCSI_QDEPTH_DEFAULT);
So I removed that change and then things compiled, booted properly, but
just froze when I plugged in the disks (including some garbled graphics on
my X screen). That patch set doesn't seem to be ok.
