"where is started" sounds as if it used to work at some point. In your
second posting, however, you note that the problem goes back at least to
2.6.13. So are there any kernels known not to exhibit the problem you
described?

So there are two problem areas: 1) the chip hangs itself without the driver
noticing and 2) the BIOS fails to bring the chip back to life afterwards.

Any difference in the kernel log when booting with (or ethtooling) a
comatose chip?

Odd. This doesn't look at all like the list I'd expect from an nforce-A939.
I thought Nvidia devices featured rather prominently in the device lists of
nforce-based boards!?
