today for some reason I've started getting lockups with 2.6 kernel + gentoo 1.4. Symptoms are kde desktop frozen, virtual terminals not working and caps lock not working. All I can find to do in such a case is to power off and on again.
I'm not sure how to debug this. After the reboot I see in the logs :-

So suspicion is with nvidia. As it happens, today I've started using an external monitor for the first time (I'm running on a Dell Inspiron 5150 notebook).
I've tried using the latest nvidia kernel drivers (1.0.5328) but I just get a white screen, so I've gone back to the most recent stable version (1.0.4496-r3).
Anything I can do to fix and/or debug further ? Problem is I can't even see any console messages since I'm still in X.
Cheers,
Pete
