Also seen in 5.12.13-300.fc34.x86_64. Disregard comment 1. Those messages were all in the form of: >kernel: intel_pch_thermal 0000:00:12.0: CPU-PCH is cool [27C], continue to >suspend The first time the kernel reports this laptop as hot is with 5.12.14-300.fc34.x86_64 but I don't see anything in the changelog that applies to pch or thermal at all.

Please retry with 5.19-rc kernel, there should be longer time delay, but the system should be able to suspend with temperature dropped. I will close this bug report because the problem should go away in 5.18-rc. Please reopen it if the problem still exists with latest upstream kernel. |
Created attachment 298091 [details] dmesg ThinkPad X1 Carbon gen 7; out of the box intel_pch_thermal is claiming CPU-PCH is hot soon after boot/startup. No fans running, battery remaining seems reasonable. Problem also happens with 5.14-rc3 but I don't have as many samples for it.
