Just for a lark, I turned off hyperthreading, turned on intel_pstate, then subjected the system to the high load encoding. No burn and crash. My (absolutely wild) guess is that the intel_pstate stuff isn't adequately accommodating the fact, when using hyperthreading, two of the "cores" are tightly connected, so the slaved "cores" end up running wild. However, I'm not familiar enough with the code to check for myself.

Best wishes,
Bob
