meanwhile i'm at kernel bootup #657, and still this crash did not 
reoccur. So it could have been some pre-existing sysfs bug that triggers 
only extremely rarely. I'd suggest that this bug have its priority 
lowered (to not hold up a v2.6.21 release) - there's no smoking gun and 
no reproducer. I'll keep an eye on it.
