I've also noticed this when I use bad 1.44MB floppies with my LS-120 drive. THe panic I get, in particular, is panic: vinvalbuf: dirty bufs and my theory is that it's choking because it has dirty bufs it can't write to disk (because of the hard errors). What do people think? I'm running 3.3-STABLE as of about 2 weeks ago. -lee -- +--------------------------------------------------------------------+ | Lee Cremeans -- Manassas, VA, USA (WakkyMouse on WTnet) | | lcremeans@erols.com | http://wakky.dyndns.org/~lee | To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
