FreeBSD fb486 4.4-RELEASE FreeBSD 4.4-RELEASE #0: Sat Nov  3 19:53:17 EST 2001     root@fb486:/usr/src/sys/compile/JEDWALL  i386

JEDWALL is GENERIC with unneeded devices removed and IPFIREWALL options added.

>Description:
486 based firewall (ipfw/natd) with an Intel EtherExpress PRO/10+ card for the outside
NIC.  I was booting it with the cat5 cable disconnected and the kernel would
panic after ex0 detection.  

ifmedia_set: no match for 0x25/0xffffffff
panic: ifmedia_set

Inside card is an NE2000 clone (ed0) and was connected.
>How-To-Repeat:

Workaround:  plug the cable back in :}
