I have a Dell Inspiron 9300 with a radeon card, using latest rawhide.
As I mentioned yesterday, I had seen these errors a few months ago but
they went away.
Yesterday I had 3 NMI's in the space of about 4 hours. In each case, I
had just selected a menu or submenu and it had just finished being
drawn to the screen.
I turned off compiz and haven't had an NMI all morning. If you're
using compiz you might want to give that a try.
That does tend to point to a buggy driver.
Could still be heat related, running the 3D engine may cause more heat
to be generated.. I've been running compiz on my Inspiron 6000 for the
last week and not seen any NMIs, but I've also not being using it for
long periods of time, as that machine has been relegated to being the
beside the couch machine...
