Thomas,

The patches you are using are the ones from november '09 i presume?
Those
patches still had a lot of SATA issues so I think they didn't make the
kernel. The patches seemed to handle SAS disks just fine though. SATA
disks was a whole different story.
I'm actually using some that Andy Yan sent me privately, I'm not sure if
they are the same exact ones he sent to linux-scsi. Probably are though.
The november patches were a set of 7 patches where only the first 6 needed
to be applied.

Srinivas Naga Venkatasatya Pasagadugula created a patch instead of Andy
Yan's patches which seemed to handle SATA disks a lot better but still
after some tests it had alot of problems. Srinivas Naga Venkatasatya
Pasagadugula is now in the process of creating a new patch to fix the
remaining issues. He told me it would take a long time to create those
and
it is now a few months ago since. I and others submitted extensive
logging
for him to check.

As for production I could only advise this:

Using SAS disks: Use stock 2.6.34 kernel + Andy Yan's patches
Using SATA disks: DO NOT GO INTO PRODCUTION.
I've been using the code Andy Yan sent me for 7 months now with 5 SATA
disks
on a md raid5 array. I haven't noticed anything serious in that time.
Prior
to tonight I had been using 2.6.32 for quite some time.

Maybe the issues only show up with serious load? My raid array doesn't get
hammered, at least not often.
The main problem was hotplugging a SATA disk. This results in a kernel
panic almost all of the time. There were more issues like the
HDIO_GET_IDENTITY failed messages during boot for SATA disks and VERY SLOW
xfs creation times.

Kind regards,
Caspar Smit

It seems to work with the change I made.

It works, but I do get a kernel warning:

At some point though I really hope this gets fixed. I'm still
willing
to help test any new versions, just that I can't keep my box down for
an extended period.
