Comment 11 for bug 507233

Ack, a reinstall? I'm still fiddling with the X server settings --- on the assumption that it is related to underclocking (it also occurred again whilst on charge). There is the Powermizer settings - but you don't seem to able to customize the hertz rate of each performance level.

It'd help if I why opening Firefox is a big cause of the crashes (but not the only one).
