Mountain Dew and doughnuts...
because breakfast is the most important meal of the day.
>Release: 2.8-current (Sep 29 snapshot)
>Environment:
System : OpenBSD 2.8
Architecture: OpenBSD.i386
Machine : i386
>Description:
This box runs as a bridging firewall, thus it has had dual
3com 905b NIC's since OpenBSD 2.5. They have always work, and
in fact work in 2.7-release, but do not work on more current
kernels.
>How-To-Repeat:
Put in two 905B's. Watch kernel do this on boot:
xl0 at pci0 dev 9 function 0 "3Com 3c905B 100Base-TX" rev 0x30: irq 9xl0:
command never completed!
address 00:50:04:8a:9f:69
exphy0 at xl0 phy 24: 3Com internal media interface
xl0: command never completed!
xl1 at pci0 dev 10 function 0 "3Com 3c905B 100Base-TX" rev 0x30: irq 10xl1:
command never completed!
address 00:19:5a:1d:84:84
exphy1 at xl1 phy 24: 3Com internal media interface
kernel: page fault trap, code=0
Stopped at _ifmedia_add+0x4e movl %edx,0(%eax)
>Fix:
Remove second NIC, watch system boot fine (dmesg follows)
