unexpected IRQ trap at vector c3

unexpected IRQ trap at vector c3

[David Coulson]

I have a box which is using a Chaintech MPM800-3 board, with a Compaq 
NC3131 dual port NIC on a PCI slot. I have been unable to get it to run 
stable for more than a day or so with the following errors:

I have tested with both a UP and SMP kernel, with similar results. 
Presently I am running it with 'apci=off noapic', although it has only 
been up for a few hours. Any information, or details as how to debug 
this issue would be appreciated.
