Bizarre bug...

From: Sascha Wildner <saw@xxxxxxxxx>

my system shows a very weird bug. Believe it or not:

I put in a Matrox Millenium G200 8MB AGP graphics adapter. As soon as I change the graphics mode to VESA_800x600 the system clock gets _fast_. 5 seconds real world time make about 1 minute system time.

- This happens with the old vidcontrol as well as with the new one. Phew! :)

- This happens only when I switch to a mode >256.

- This happens only with the Matrox card. We've tried reproducing the behaviour on a friends machine (by booting my kernel) but it worked fine. He has an nVIDIA adapter. Are there any Matrox Millenium AGP users out there?

Since I wanted to have a look at the vesa/syscons stuff anyway I'm rather looking for some gentle advice how one would go about finding the bug. I'm still an amateur debugger.
