I've also tried 5.16.11, 5.16.12 and 5.16.13 and they also show the
same issue (overheating while suspended).

I could not spot any difference between the dmesg messages issued
during suspend between a working version (5.16.9) and the the broken
ones (5.16.1[0-3]).

I've bisected the regression down to commit 4287509b4d21
https://lore.kernel.org/lkml/20220214092510.074083242@xxxxxxxxxxxxxxxxxxx/

I have also tried reverting that change on top of 5.16.12, and the
overheating behavior is gone.

OK, so it is not clear if this is a regression in -stable only or in the mainline.

Would it be possible to try 5.17-rc7 and see if the issue is still there?
