ABIT AX78 freezes constantly

[dmitri1973]

Ubuntu freezes during installation or shortly after the startup (i can see the desktop though).

Tested:
Ubuntu 7.10 (both 32 and 64), 8.04 (both 32 and 64)
Fedora 8 (both 32 and 64)
- same symptoms for the all listed above: even if the luck is on my side and i managed to install a distribution then the system freezes after a couple of minutes (even without any interaction)

Damned winxp works fine of course.

AMD X2
ABIT AX78
PowerColor 1950PRO
Samsung 250G SATA2

Is there any way to find out WHY?

This motherboard has 2 PCIE 2.0 slots... Can that be the reason? I mean does a linux support all these new features?

But I use only one slot though...
