unexpected IRQ trap at vector c3

From: David Coulson
Date: Sat Mar 12 2005 - 18:04:33 EST

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.
