This would appear not to be a radeon firmware issue:
md5sum /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.
