I get the following on startup:
=====================================
[ BUG: bad unlock balance detected! ]
-------------------------------------
start_udev/197 is trying to release lock (&sd->s_active) at:
[<0000000000209024>] release_sysfs_dirent+0x8c/0x118
but there are no more locks to release!
other info that might help us debug this:
no locks held by start_udev/197.
