Looks like it is a DMA issuw.  Syslog is full of messages like this (I guess I 
should have looked there first):

Dec 12 14:11:11 df13 kernel: hda: DMA interrupt recovery
Dec 12 14:11:11 df13 kernel: hda: lost interrupt
Dec 12 14:11:11 df13 kernel: hda: dma_timer_expiry: dma status == 0x64
Dec 12 14:11:11 df13 kernel: hda: dma_timer_expiry: dma status == 0x64
Dec 12 14:11:11 df13 kernel: hda: DMA interrupt recovery
Dec 12 14:11:11 df13 kernel: hda: lost interrupt
Dec 12 14:11:11 df13 kernel: hda: dma_timer_expiry: dma status == 0x64

I guess I'll email the Admin and write this machine off for now.
