Andy,

Sounds like a page fault trap.  UVM is the BSD virtual
memory system, meaning it manages the swap file. 
Among the things that can cause a page fault is a bad
sector on your swap partition, but a driver bug can
cause it as well.  At this point I would be talking
out of my hat if I go any further.  Perhaps others
have ideas about eliminating the possible error
sources.
