Re: [PLUG] How to diagnose a lockup?

Didn't mean for that LinuxMCE DVR reference to be confusing. It's just a 
linux pc acting like a Tivo. Otherwise, it's a normal machine running 
Kubuntu 7.10.

Ctrl-Alt-F1 doesn't get me back to terminal, but I didn't try killing 
the Xserver.

I guess I thought someone could tell me something like "reboot, look at 
these logs in this order, etc." Or "reboot and use tool x to get a dump 
of y," or just outline a general strategy for diagnosing the issue, or 
finding out what the machine was doing right before the lockup, etc.
