Memory was my first suspicion.  I started with 2x2GB of Kingston memory:

spdmem2: DDR3 SDRAM, no ECC, no temp-sensor, 2GB, 1333MHz (PC3-10666)
spdmem2: 11 rows, 13 cols, 8 log. banks, 2 phys. banks, 1.500ns cycle time
spdmem2: tAA-tRCD-tRP-tRAS: 9-9-9-24


When the problems first manifested, I replaced that with 2x2GB from 
Corsair:

spdmem1: DDR3 SDRAM, no ECC, no temp-sensor, 2GB, 1333MHz (PC3-10666)
spdmem1: 12 rows, 13 cols, 8 log. banks, 1 phys. banks, 1.500ns cycle time
spdmem1: tAA-tRCD-tRP-tRAS: 8-8-8-24

I'm currently running with all 8GB installed.
