I wouldn't read too much into that - that's just the last file from
sysfs that's been touched. Unless you've some other reason to suspect
sysfs is related I'd doubt there's anything to connect the two.
Here goes. Looks like PA may be involved (I've had it crash a
lot
lately).
PA looks like an innocent victim (or if it is in any direct way
implicated it is just triggering a kernel bug that was already there -
userspace should not be able to make the kernel GPF).

Are the crashes you're seeing always in this set of functions (same
backtrace) or are you getting variations?
