  I've updated the BIOS in response to this issue, but it still continues:

  This would appear not to be a radeon firmware issue:
  md5sum /lib/firmware/radeon/PITCAIRN_rlc.bin
  3d2c150b3626419131bbc9a5864c7f1d  /lib/firmware/radeon/PITCAIRN_rlc.bin
  
  Hence, as there are no extra packages available for the Ubuntu provided
  mainline kernels, I won't be able to test to this issue with the
  mainline kernel in the exact environment this problem is reproducible
  in. I've uninstalled virtualbox, and tested this with 3.18.1 for 3 days
  and have had no crash so far. However, the meaning of this result is
  inconclusive at best.
