Hello,

I see a load of these after booting into 2.6.33.1-rt11:

BUG: sleeping function called from invalid context at kernel/rtmutex.c:684
pcnt: 1 0 in_atomic(): 1, irqs_disabled(): 0, pid: 1507, name: md1_raid5

As these appear to be touching my raid array I am quite eager to learn
how I can fix the BUGs.

Please have a look and explain.

Kind regards,
