The first thing that I would do is try to figure out who holds the allproc_lock. If the lock is held exclusively then the pointer to the thread struct will be in allproc_lock.sx_lock. If the lock is held shared then it gets trickier. I'm not sure if there is a better possible way than doing a thread apply all bt in kgdb and finding which stack(s) could hold allproc_lock. _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
