Subject: Reboot regression on Lager
Date: Wed, 23 Dec 2020 19:53:04 +0100	[thread overview]
Message-ID: <20201223185304.GA75038@ninjato> (raw)

[-- Attachment #1: Type: text/plain, Size: 6180 bytes --]

Hi,

I just discovered that my Lager can't reboot anymore. 5.10 is good,
current Linus' tree [1] is bad. I don't have time to debug this on my
own right now, so this is a reminder and notification for now.

[1] (614cb5894306 ("Merge tag 'acpi-5.11-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm")

Happy hacking,

   Wolfram
