Just to reiterate; I can reliably hang the 466 running with this firmware within a few minutes under the 'amr' driver, while the Dell 3.00 firmware doesn't demonstrate the config-time hangs on any system I've run it on and is also not susceptible to the hang problems. I've been a little distracted with various Mylex-related issues for a little bit now, and am still waiting for some response from AMI before returning to work on these problems. I'm also in need of a more or less permanent loan of a 434 or 438 (preferably) controller as all I have right now are 418/428/466 and Karsten's been reporting issues with all of the 438's firmware. -- \\ 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
