Thanks for the fast response.  I toggled turned off WITNESS (and turned on 
DDB), and I got the same response.

I tried digging some more.  I know that there was an issue earlier with the 
via 8237 and dma, so I tried disabling dma (hw.ata.ata_dma=0).  This had no 
effect.  I'll attempt to dig around in the PCI driver and the ata driver a 
little more and see if I can add some traces around the interrupt assignment.  
Any additional suggestions would be much appreciated.

Great Cthulu sig.  I'm a bit of a H.P. Lovecraft fan myself.

Thanks,
