Hi Andi, I am experiencing the same crash using E5-2658v3 CPU in our lab in Chandler. I can
provide remote access for you to take a look.
Also, I used your ucevents.py to check out IRP counter, and it looks like
it's reporting half of what I'm expecting. Do you know if the script/PMU
program for both IRP0 and IRP1?
