These continue and have never stopped. Would someone please comment. Is this a kernel error or mdadm error? Kernel is latest 3.0 and latest mdadm with patch for 3.0 kernels.

Does this still continue? A recent build of mdadm was added to rawhide that updated mdadm to 3.2.2 and might have resolved the issue.
Fixed, closing. Thanks.
