Ok. So.... I've now evaluated this. My observations;

There is very little difference between my kernel and stock temp-wise, running on idle, light use or during game play / other cpu intensive tasks...

(note: these temps won't reflect yours - different climate / environment - I'm comparing the kernels - not your device vs. mine)

on idle: 27-33°C (both kernels, although mine does tend to jump a bit more than stock... I actually have a good idea as to why that is - but will address that later).

while using my phone (just browser or clicking around) both kernels would bounce between 35-40+°C ... i observed little to no difference... and certainly my kernel wasn't idling at 40-50°C and stock definitely does NOT sit at 30°C while in use...

Playing the marvel game for a while on each kernel, watching all of the temperature sensors (5 && 7 tending to be the hottest)... I observed both stock and my kernel hitting similar peak temps....

next, I used my own proaudio apps to create higher load than those games create..... I also set to performance governor (no frequency scaling), both kernels had similar peak temps.... Finally, I ran geekbench - same thing; not very much difference in temps....

All of this was done without being plugged into my charger, while in use ~ as that WILL increase temp being as the battery tends to warm up ~ causing the whole device to heat up (including cpus).....and obviously, your phone gets warmer when the cpu cores are busy anyway....

My kernel may have been a few degrees warmer - but certainly not 10-20°C, in any of the scenarios that I tested.... I'm not sure how you evaluated this or came to these conclusions, if there were different variables that I'm not aware of, etc.... But yeah, I have my doubts that stock is running significantly cooler than my kernel... I wasn't able to produce any results that showed a clear huge difference....

What I will note though; I'm not running the stable kernel ~ and plan to replace it later today.

K. thanks... I had a quick look and see what happened, but I'm going to have to spend some time getting to the bottom of it... I'd really like to be able to reproduce it too ~ not sure if that's going to happen though.

thanks for getting that info to me.

It's the least I can do...

And no worry nor hurry, there's nothing bothering me in these random hangs.
[Google Pixel XL ROMs, Kernels, Recoveries, & Other] :
Oh they bother me (lol), especially since I have a hard time reproducing....

EDIT: I'm pretty sure I found the issue and have a good idea of how to fix it. Not promising an immediate fix ~ but I'm reasonably sure this particular issue will be fixed sooner than later.
