I also do a kernel compile loop burn in test on my machines (first
sugested to me by the honorable Donald Becker oncE :) )

I have used the same g400 in two machines, both able to compile the kernel
with -j4 for days. As an aside, on one of these machines I actually forgot
I was compiling the kernel for a few days as she still performed well :).

The card worked fine for several months under 6.2 XFree86 3.x. Once I
upgraded the first machine to 7.0 and played around tiht XFree86 4.0 and
dual-headed (perhaps the real problem there) It started locking up. Even
when I went back to single headed, and the original mga driver it
continued to lockup. It is not locking up now with an ATI card.

I did some brief testing on a new machine (but with the same card) and it
locked up after leaving it overnight. This could very well have been an
apmd issue since I hadn't completed configuring the box. I will be redoing
the burn in test when I get it back, and will report on it's stability
too.

But, I do see something common amongst these machines (with
lockups). They are all athlons. this may be pure coincidence.

My "old" system:
Microstar MB
Athlon 500
Adaptec 2940U2W
2 x IBM 9GB LVD drives
Matrox G400 32MB
lynksys or netgear thernet
SB 64 sound (i think)

My new system:
Asus K7M MB
Athlon 800 (only reported 550 so I sent her back)
Adaptec 29160
Seagate 160 drive 18GB
Matrox G400 32MB (same card as above)
3com nic
some built in sound - not configured
