FreeBSD flodhest.uio.no 4.6-STABLE FreeBSD 4.6-STABLE #0: Wed Aug 7 16:57:41 CEST 2002 root@flodhest.uio.no:/usr/obj/usr/src/sys/GENERIC_DEBUG i386
P-133 Intel CPU, 32 MB RAM, ata drives and CDROM. 3Com 3C900 card, no
known IRQ conflicts.
>Description:
Sending any type of IP packet to the IP assigned to xl0 (3COM 3c900 card)
provokes a kernel panic.
Both packets send from the FreeBSD box and external computer provokes the kernel panic.
(Fatal trap 12: page fault while in kernel mode)
Newly installed system with 4.5-RELEASE and CVSUP'ed stable and ports
collection. Ran buildworld, installworld, buildkernel and installkernel as the handbook recommends.
booting the kernel with boot -s provokes the panic without before console is accessible.
Botting the kernel in multiuser mode, and the going to single user with
shutdown now does *NOT* provoke the panic, nor am I able to provoke
any panic in this configration, I can even ssh, ping , run dhclient and
browse with the xl0 interface. But *only* when booting in multiuser mode, and then entering single user mode.
>How-To-Repeat:
Send any IP packet to xl0 interface. Works every time *except* when dooing the multiuser boot and droping down to singel user.
"Look ma!, it's a DOS OS ;)"*cough*
