Subject: Many reports of laptops getting hot while suspended with kernels >= 5.16.10 || >= 5.17-rc1
Date: Wed, 9 Mar 2022 14:44:30 +0100	[thread overview]
Message-ID: <31b9d1cd-6a67-218b-4ada-12f72e6f00dc@redhat.com> (raw)

Hi Rafael,

We (Fedora) have been receiving a whole bunch of bug reports about
laptops getting hot/toasty while suspended with kernels >= 5.16.10
and this seems to still happen with 5.17-rc7 too.

The following are all bugzilla.redhat.com bug numbers:

   1750910 - Laptop failed to suspend and completely drained the battery
   2050036 - Framework laptop: 5.16.5 breaks s2idle sleep
   2053957 - Package c-states never go below C2
   2056729 - No lid events when closing lid / laptop does not suspend
   2057909 - Thinkpad X1C 9th in s2idle suspend still draining battery to zero over night , Ap
   2059668 - HP Envy Laptop deadlocks on entering suspend power state when plugged in. Case ge
   2059688 - Dell G15 5510 s2idle fails in 5.16.11 works in 5.16.10

And one of the bugs has also been mirrored at bugzilla.kernel.org by
the reporter:

 bko215641 - Dell G15 5510 s2idle fails in 5.16.11 works in 5.16.10

The common denominator here (besides the kernel version) seems to
be that these are all Ice or Tiger Lake systems (I did not do
check this applies 100% to all bugs, but it does see, to be a pattern).

A similar arch-linux report:

https://bbs.archlinux.org/viewtopic.php?id=274292&p=2

Suggest that reverting 
"ACPI: PM: s2idle: Cancel wakeup before dispatching EC GPE"

which was cherry-picked into 5.16.10 fixes things.

If you want I can create Fedora kernel test-rpms of a recent
5.16.y with just that one commit reverted and ask users to
confirm if that helps. Please let me know if doing that woulkd
be useful ?

Regards,

Hans
