It looks like there's an unexpected ATA interrupt.  I can't think of
any reason why either sound or netgraph would cause this - neither
should be touching the hardware directly.  Unless someone else has
seen this before, tracking it down could be time-consuming.

I think you'll need a serial console to continue.

Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
