- Fix 3dfx fb crash with high pixelclock        (Jurriaan on Alpha)

I see that there is a 3DFX fix with high pixelclock.

Without the fix, could this be a reason why my machine locks up when
I am scrolling through various MPG or DIVX movies with mplayer
(sometimes)?

I have a 3DFX Voodoo 3 3000 AGP.

I wrote the fix, so here goes:

the fix only applies if you run your DAC at over half the maximum speed.
That means that with a Voodoo 3 you'd need a 150 MHz pixelclock to
trigger it. If you run linux using no framebuffer or a framebuffer at
frequencies below that, nothing is changed, and you'll need to find
another culprit. If you run above that, you could try to copy in
tdfxfb.c from the previous version. If that fixes it, I've got a
problem.

Anybody with a voodoo card and running high-frequency framebuffer:
please post your experiences.

Thanks,
Jurriaan
