Re: 6.9/amd64 runaway acpi process on Thinkpad T580

[Daniel Wilkins]

I've ran into this on my T480, it seems most consistently triggered by power
cycles caused by running out of battery. The bug's existed for quite a few
years (I think I first noticed it in 2019.) If I recall correctly I've
posted it to the list a couple of times but I don't think any concrete answers
ever emerged; your report is more thorough than mine were though.
I do remember that it never happened on my T430, but that's quite the
hardware gap.
