sorry for the late followup how does latest 2.6.32-8 behave for your
tests?

Bram,
did you test a current 2.6.32 kernel?

Cheers,
Moritz

Default Bug#551804: linux-image-2.6.30-2-686: Booting with PAT enabled crashes kernel in OpenGL apps

Hi there,

Sorry for the late reply. I tested with kernel package
linux-image-2.6.32-5-686, version 2.6.32-15, and I can't get the
kernel to crash anymore, nor can I get Processing -- the app I was
using to test OpenGL -- to exhibit any strange behavior, so I suppose
this bug may be closed.

Cheers,
Bram
