Data point:  I have trouble with an (oldish) via box too.

processor       : 0
vendor_id       : CentaurHauls
cpu family      : 6
model           : 9
model name      : VIA Nehemiah
stepping        : 3

It has a quite interesting error pattern:  It runs rock solid in summer, 
it has stability issues in winter.  It is located in a server rack in a 
basement, so the weather out there shouldn't make a big difference to 
the machine.  I'm really curious what this might be ...

"stability issues" means it does either lock up or reboot, usually 
without anything on the serial console.  Seems to be more likely under 
load.  The periods of time the machine runs can range from hours to weeks.

cheers,
   Gerd
