(In reply to Stéphane D'Alu from comment #26)
Looking at both tickets on this issue, the thing that jumps out at me is that
it appears that only Lenovo systems are impacted. Lots of different ones have
been reported, but no Dell or HP systems. No Asus, It is clearly something that
ONLY impacts Lenovos and it looks like it can be further constrained to
ThinkPads. I find no references to IdeaPads or other Lenovo lines. Last I knew,
development of ThinkPads was still in the US at the former IBM facility. Looks
like something unique to those systems, which is clearly distinct from other
laptops. I just can't begin to guess what.

This is WAY beyond anything I can troubleshoot, but I'm more than willing to
help test. My L15 has been a real pain, unlike every other ThinkPad I've used
(and that is going back to at least 1995). I suspect that this will require at
last on and maybe two very top-line FreeBSD folks to track down. kib or jhb,
perhaps? Now that 13 is out the door, there will only be more reports and I'd
really like P-States.
