Actually, I don't think so. I'm not 100% sure, but I think that you end up in the interrupt handler for the card that's going away, but with tty interrupts masked so you can't get back into DDB. If it's a modem card, then you'll have them masked as well. I'm _fairly_ sure that you'll find you're spinning in the card's interrupt handler. Stick a printf or two in there and see for yourself. -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
