I'm a bit late on this discussion, but the only time I had something
like this happen was when the network hardware and the video hardware
and a few others were sharing the same interrupt. One at a time things
would work, put them together and it would fail.
There were some magic kernel options at boot time that made the problem
better, but eventually I got rid of the hardware.
So it could be a bios or kernel setting as well.

It is not this day!
