Comparing the commission logs from the old kernel and current kernel it
seems the new kernel is hitting a different issue now

The 3.13.0-46 kernel is getting a panic with an NIP of:
power7_enter_nap_mode

The 3.13.0-27 kernel was dumping a trace on what looked like a H/W error:
 EEH: Frozen PE#5 detected on PHB#1

It would be good to know if Utopic and Vivid are getting a panic in the
same way.
