Subject: 2.6.33.5 rt23: sleeping function called from invalid context

After a suspend/wake up cycle, just after upgrading to fc12 (I did not
see this with the same basic kernel - that is, compiled from the same
source + patches - under fc11). 

BUG: sleeping function called from invalid context at
kernel/rtmutex.c:684
pcnt: 0 0 in_atomic(): 0, irqs_disabled(): 1, pid: 10582, name:
pm-suspend
Pid: 10582, comm: pm-suspend Not tainted
2.6.33.5-120.rt23.1.fc11.ccrma.i686.rtPAE #1
