Thanks for the detailed instructions, both of you. I'll see that I can collect some information next time this happens (I can't really reproduce it, it just happens about once a week).

VTY switching works at first (even switching to and from the running Xorg), but eventually that stops working too. Haven't tested pings, I'll try that next time. As for the serial console... I guess I can get that working. I wanted to buy an USB->Serial adapter for my laptop anyway (no, it's not the laptop that's freezing, but the desktop machine, which does have a native serial port). Happy Holidays! Benjamin
