The output of a trace is as follows: Debugger(c02a0dbb,c3286f00,c050f880,c33f5f50,c017f4d7) at Debugger+0x42 panic(c02a23d2,c3286f00,c050f880,820f144,c33f5f70) at panic+0x74 sbappendaddr(c3286f44,c02f9630,c050f880,0) at sbappendaddr+0x2b div_input(c050f880,14,c050f880,8169bc,820f144 at div_input+0x12a ip_input(c050f880) at ip_input+0x69f ipintr(c024dab3,0,27,27,820f144) at ipintr+0x4b swi_net_next() at swi_net_next I hope this helps somewhat. If I was supposed to issue other commands at the db> prompt, please inform me of such, and I will gladly do so, I apologize for having no previous debugging experience. Is there anyway to get this output I have placed above dumped somewhere? I manually typed that into another machine while experiencing the panic, and I will admit, I made a few mistakes the first pass. It took me a second pass to be sure it was correct (damn those f5f's), but I am 100% certain at this time that it is exactly what was displayed as the output of trace at the prompt db> - Jay Oliver kythorn@scorched.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
