Hello,
I have a problem with my hw and I'm not sure how this happens.
I had a Matrox Mystique for 2 years and the computer ran fine. Now I switched to a
Matrox GA400 and the trouble started. I got corrupted blocks on my HW, that's a
'little' annoying. I post information from /proc and syslog:

I hope you can help me to find the problem. The machine worked until yesterday, now I get
these data phase errors and corrupted blocks (seems a hw conflict?!??).
Thomas.
