I haven't, but the first thing I'd do in the situation you describe is
update the firmware on the RAID card.
I looked around at other discussions of the same error, and it looks
like some people have also resolved that problem by switching to the
deadline scheduler
# echo noop > /sys/block/sdb/queue/scheduler
...but I wouldn't do that unless you update the firmware and still see
the error.
