Hi, I'm writing to report a problem that's occurring in the raid456 module.
I'm running vanilla linux with real time patches applied
(http://rt.wiki.kernel.org).
Since I upgraded from 2.6.31.12-rt12 the following message comes frequently.
Before there weren't such messages:

According to Neil Brown, this problem was introduced by the real-time patches.
This is a root-on-raid5, 3 disk-IDE-attached setup. If you need any more info
let me know. Please CC me any replies as I'm not subscribed.
