could you please try the patch in http://marc.info/?l=linux-raid&m=149967155905878&w=2?
That patch works nicely. I just finished two concurrent raid checks plus some writing without any issues.
there is a new patch which I'll apply to upstream. It should fix the problem too, but if you can test, we have more confidence. Thanks! http://marc.info/?l=linux-raid&m=150002013125258&w=2
