Unfortunately I have to confirm the issues on my brand new 13v2 with TPM after coreboot update. I installed Qubes 4.0-rc4.
- fans behaving erratically
- sudden power-off on high CPU load
Before installing Qubes and updating coreboot with default PureOS installation I had one instance of:
- closing lid and witnessing it draining battery over night
At one point I was able to reliably reproduce issue #2 by booting into Qubes, starting Terminal in one existing fedora-based Qube and doing yum install curl. It was enough to power-off my notebook 2 times in a row. And third time I was able to bring “sensors viewer” app up, decreased update interval to 1s and observed CPU temperatures. The numbers were wildly jumping between 70 to 100 degrees celsius (according to the sensors viewer). I switched to sensor type coretemp-0 and observer all three sensors before doing another yum install and as soon as all three sensors Package id 0, Core 0 and Core 1 hit 100 my laptop did power-off. Interestingly enough before that happened some of them were flirting with 100 but notebook shut down only when exactly all three got to 100.
I don’t think it is physically possible for that temperature to go from say 80 to 100 in matter of a second. There must be something wrong with the readings and that would also explain #1, because fans simply switch on/off based on those wild values.
