Hi,
over the last 6 months or so, I have been so unfortunate to experience
spontaneous reboots when I restart netif.
Most of the time it leaves no trace in logs, but this time I was "fortunate"
enough to be able to scrible down something while in console.
I hope someone can shed some light on this - and I will be happy to provide
a config files if necessary - it's basicly a standard setup with
iwi0, wpa_supplicant connecting via wpa. It is a T42 with a Intel 2200BG.
There is no issues in other OSes, so I figure this to be a driver specific
problem. This is from handwritten notes, so there may be some inaccuracies.
It is FreeBSD 8.0-release.

Automatic reboot in 15 seconds - press a key on the console to abort.
