Hi all,
I am getting panic()s upon each shutdown (visibly after disks have been
synced). kgdb reveals the at /usr/src/sys/kern/kern_mutex.c:335
_mtx_lock_sleep() as the culprit.
Running 7.0-RELEASE with root mounted from a ZFS file system. Seems to
only have started since creating a second raidz data pool (mia-data),
yet dismounting this before shutdown does not stop the panic().
