The following reply was made to PR kern/16808; it has been noted by GNATS. From: Dan Papasian <bugg@bugg.strangled.net> To: engarcia@fis.cinvestav.mx Cc: freebsd-gnats-submit@FreeBSD.ORG Subject: Re: kern/16808: Fatal trap 12, kernel does not boot Date: Mon, 21 Feb 2000 11:54:03 -0500 You should try to remove the options you don't need from your kernel to eliminate some possiblities. I took the time to comment on which entries in your kernel configuration were _very_ wrong. Scroll down.

Don't expect LINT to give you a working kernel. Strip down GENERIC by removing all of the hardware you don't have, and then use LINT to add hardware that you haven't but isn't in GENERIC. Fix up your kernel, and come back if it still doesn't work. -Dan Papasian <bugg@bugg.strangled.net> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
