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.
