Anything that might help locating the nature of the "lockup". A scope on the bus would be helpful, sure. Some idea where in the kernel the CPU was executing would be good. The values of cpl and ipending are always informative. Basically though, you're saying "I have a problem with an old version of freebsd on some sorts of hardware. Is it fixed?". There's no possible way for anyone else to answer such a totally vague question. -- \\ 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-hackers" in the body of the message
