Sometimes noise or other problems can cause NMI's with poor motherboard designs. I seem to remember stray DMA requests can sometimes trigger an NMI. Has anyone seen parity on the cache? It's probably not FreeBSD to blame - it is more likely FreeBSD is revealing a latent weakness in your system. Does anyone remember if NMI is brought out to the ISA bus? This would open up all kinds of possibilities. ====================================== When philosophy conflicts with reality, choose reality.
