Broadwell i5-5675C + Intel GFX (Iris Pro 6200)

No KP - it just spontaneously reboots..

That is the primary symptom for a panic.

That is the primary symptom for a panic.

Just did not get any verbose output - like I do when it is panicking on boot with -v...

I have now been looking at the temperature - when running normally, I can start LuxMark a few times in a row - temperature going up after each run (IGPU only). Starts around 65°C, ends around 75°C. I then started to move windows etc, to also busy the processor - and bam...

Same happens after few seconds running LuxMark with both processor and IGPU...

I do actually have some Crashreporter stuff (possibly did not see it earlier) - its in /Library/Logs/CrashReporter.
What should I look at there?
Thanks...

95°C is when problems begin

What should I look at there?

What is there?

possibly connected: I added an SSDT for my processor at some point...

CPU PM, not likely.

CPU PM, not likely.

It does not make a difference whether its there or not...
Have you got any ideas? Should I restore 10.14.2 and see if the problem was there as well?
Running GeekBench is no problem (temperature does not rise much there, too).
What else could I try to challenge IGPU & processor - to see whether it is a load issue...
Or do you suspect a LuxMark bug? Shouldn't cause such panics...?

CPU PM, not likely.

It seems to be connected to heavy load on CPU and GPU:
iTunes with Visualizer on caused a panic/reboot after few 10s of minutes.
No reboots without load... (so far)

Suggests hardware problem, run MemTest
