Recent kernels freezing on Via C3?

Hi folks -

Recent kernels seem to be freezing after some time on Via EPIA i586 machine.
Tried with:

 - vanilla 2.6.8
 - kernel-2.6.8-1.584

Although I am compiling and trying to get to work wifi drivers at the moment,
with the Vanilla 2.6.8 I was using one card/driver and with -584 another, so
I doubt they both have the same crashing problem.  Machine works normally and
falls over after some time, completely unresponsive.

Happened to be running slabtop when it fell over last time, since the driver I
was trying to get to work had problems allocating ~40K of dma-able memory.
Don't know if that has any clues.
