Ive tried 5 different kernel configs now , none of them was without de0 wich I assume might be causing this. Any hints ? btw what is the diff between next and step really , Ive never used the kernel debugger before , though it has alot of resemblance to asm-one's debugger I used on the amiga years ago :) /Khaled, Telia Network Services Mail: khaled@telia.net Cell: 070-6785492 Work: 08-4567281 :hacker: /n./ [originally, someone who makes furniture with an axe] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
