This patch addresses a number of weird behaviours observed
for the sata_mv driver, by fixing an "off by one" bug in processing
of the EDMA response queue.

Basically, sata_mv was looking in the wrong place for
command results, and this produced a lot of unpredictable behaviour.


2.6.16 with this patch and your former patch applied, crashes during
stressing a raid5 connected to a MV88SX6081.

2.6.16-rc6 crashes too.

2.6.16-rc6-mm2 is rock solid wrt sata_mv.

I get no output of the crash on netconsole. Would it help if I get the
output of the crash (if any)? In that case I'll connect a screen and see
what it produces.


Yes, most helpful, please.
Even a digital camera snapshot of the oops would be handy to see.

Thanks!
