 Tried some more things.  I added a bunch of printf statements in the ATA 
 code to try and see where it crashed.  It died in the *middle* of a printf 
 in ata_sii_reset (i.e. it only printed part of the message).  Then I added 
 some printfs to some of the interrupt handling functions (sata_interrupt, 
 sata_generic_intr, etc) and it didn't crash anymore.  So I guess that 
 something is timing dependent.
 Any ideas?
