Bizarre bug...

[Sascha Wildner]

Hi,

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.

Regards,
Sascha
