The first results from the Fedora test kernel builds are in: "HP Envy Laptop deadlocks on entering suspend power state when plugged in. Case gets very hot and requires a power button hold to restart" https://bugzilla.redhat.com/show_bug.cgi?id=2059668 5.16.9: good 5.16.10+: bad 5.16.13 with "ACPI: PM: s2idle: Cancel wakeup before dispatching EC GPE" reverted: good 5.17-rc7 with "ACPI: PM: s2idle: Cancel wakeup before dispatching EC GPE" reverted: good 5.17-rc7 (plain): good So this seems to match the arch-linux report and the email report you linked. There is a problem with the backport in 5.16.10+, while 5.17-rc7 is fine. > It is likely that the commit in question actually depends on some > other commits that were not backported into 5.16.y. I was thinking the same thing, but I've no idea which commits that would be. Regards, Hans p.s. I've also gotten results in for: "Thinkpad X1C 9th in s2idle suspend still draining battery to zero over night , Appear from Kernel 5.16.10" but the results there are mixed. There might be some EC firmware issue in play there. I'm getting the feeling that on the x1c9 there really are 2 issues which both only trigger sometimes, making testing this problematic. One of those 2 issues is likely the same 5.16.10+ issue reported on laptops from other vendors.
