CAMDEBUG is already on, but simply opening/closing the targ device,
without sending any ioctl to enable it, shouldn't produce any CAM
message. I traced the kernel thread and I found that it doesn't return
from the destroy_devl() function: csw->d_purge is NULL and
dev->si_threadcount is '1'. The thread enters the following block
(kern_conf.c, row 690) and never exits.


	while (dev->si_threadcount != 0) {
		/* Use unique dummy wait ident */
		msleep(&csw, &devmtx, PRIBIO, "devdrn", hz / 10);
	}
