A5200 slow after applying 109962-12

entire array (or loop, meaning multiple arrays). The good fix used to be
to make sure all revs were up to date. Not only that, but usually a bad
disk would cause IO problems like I am having after applying this patch.
Anyone seen this?
Should I downrev?
How is that done?
iostat xtcn shows service times and busy times way too high for this kind
of IO load:

the 9G drives are doing a bit better (but seems like might be affected as
well) (rev: 1129->1229)
