As before, this patch is against 2.6.22 with no other patches needed nor

In this revision, interrupt handling was improved quite a bit,
particularly for EDMA. The WARNING in mv_get_crpb_status() goes away,
because that routine went away. Its EDMA handling was potentially racy
as well. It was replaced with a loop in mv_intr_edma() that guarantees
it always clears responses out of the queue, not a single response.
Here's hoping that the WARNING in mv_qc_issue() goes away as well, but I
am less than 50% confident that will happen.
The driver is making substantial progress with all these improvements,
though, in searching for the cause of this hardware behavior :)
Though if mv_qc_issue() still warns, I would be interested to know if
this driver works OK if the mv_qc_issue() warning is simply removed at
that point...
oh very nice... no warnings on boot, and no warnings while i "dd
if=/dev/sdX of=/dev/null" and i'm seeing 74MB/s+ from each disk on this
simple read test.
for lack of a better test i started an untar/diff stress test on the
disks... we'll see how it goes. (it's based on doug ledford's
memtest.sh)
Thanks for the testing. Looks like we might have hit on something good...
