Hi,
Please take a look at
https://bugzilla.kernel.org/show_bug.cgi?id=13594
As it seems to refer to the same issue.
A patch is referred on the bottom of the bug page, but I haven't tried
it yet.

Do note that this probably won't do you any good on the long run. I
have this issue and I've seen it kick out several drives in a row, so
you can end up with a dead array even it it's raid6.
Please let me know if you have any luck with any of the pacthes, and
I'll do so also.
Best regards.
