Hi Alan -
Recent kernels, and a vanilla 2.6.8.1 from kernel.org compiled with the
development tree compiler, both don't last very long on my Via C3 box. It's
definitely NOT hardware or heat, since the same board physically untouched
runs for months solid on 2.6.7-1.437, right now a 5 day uptime since the last
time I tried one of these more recent kernels. Symptoms are frozen solid.
256MB on the thing. I was running slabtop on it last time it died, looking
for why a driver was not able to allocate ~40K of dmabale memory, here is
what was left unscrolled.
