I have a 3.3-stable machine that I use as a news router (running diablo). The
fxp0 interface averages 10-15 Mbps bandwidth continously.
About once a week the machine crashes & reboots. We enabled the debugger this time
and captured the following debug output:
Fatal trap 12: page fault while in kernel mode
