I'd avoid making wild-assed assumptions like this, which have no basis at all in fact and only spread disinformation. The simple fact is that the 'net' and 'tty' interrupt masks prevent interrupts during critical regions in the respective code sections, and a driver which is going to call into those regions needs an appropriate mask to avoid corrupting them. "It works for me" means "I have been lucky so far", and nothing more. Note also that the entire problem is meant to be addressed in the most recent ppc work, but I don't hear anyone here reporting the results of their testing of it... -- \\ 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-questions" in the body of the message
