Subject: bug#62711: Suspend-to-disk with LUKS-encrypted root doesn’t work
Date: Fri, 07 Apr 2023 14:42:58 +0200 [thread overview]
Message-ID: <87y1n3dfsd.fsf@inria.fr> (raw)
Hello!
Since my laptop’s battery died, I set up suspend-to-disk as documented
in the manual (info "(guix) Swap Space"). I use a swap file on top of
my LUKS-encrypted root partition, so I added:
"resume=/swap"
"resume_offset=OFFSET"
to my ‘kernel-arguments’ field, where OFFSET is given by ‘filefrag’.
However, when resuming, it looks as though the kernel is not even trying
to resume:

Hibernation (with ‘echo disk > /sys/power/state’) did seem to succeed,
with this one message:
--8<---------------cut here---------------start------------->8---
Apr 7 12:39:30 localhost vmunix: [14219.893014] PM: hibernation: hibernation entry

Am I missing something?
Thanks,
