This might be due to a patch in the sysfs core that needs to be fixed,
or it could be a deadlock.  Look at the codepath where we are removing a
device by writing to a sysfs file and make sure we aren't deleting
ourself.  If we are not, it's ok, if we are, we need to fix that to use
the proper api calls to do this safely.

Hope this helps,
