I can say it's a "me too" on mine, however I never reported the issue as
it's a known problem:
http://marc.info/?l=linux-raid&m=123606440522693&w=2
I ran into it on a USB key RAID setup when I started up a huge rsync. I
didn't even get a trace in that situation, just a hard lockup.
Not looked at it since.
