Hi,
I exepience issue similar to discussed in next thread
https://lists.gnu.org/archive/html/bug-guix/2016-07/msg00087.html
My laptop can't wake afterr sleep and hibernate.
I use GuixSD on libreboot x200. Issue was checked with linux-libre kernels 4.1,
4.8, 4.10; with libreboot 2015-01-26, 2015-05-18, 2016-09-07; with and
without "resume=/dev/sda2" option (my swap partition on /dev/sda2).
I can't resume neither from suspend to ram nor from suspend to disk.
I start hibernation with "echo disk > /sys/power/state" command. On next boot
image does not restored. I can see that image was saved:
# swapon /dev/sda2
swapon: /dev/sda2: software suspend data detected. Rewriting the swap
signature.
In boot log I can see next message:
[ 0.610581] PM: Checking hibernation image partition /dev/sda2
[ 0.610598] PM: Hibernation image not present or could not be loaded.
...
[ 1.063943] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled,
doesn't support DPO or FUA
[ 1.108500] sda: sda1 sda2 sda3
[ 1.109780] sd 0:0:0:0: [sda] Attached SCSI disk
Looks like PM try to find hibernation image before attaching hard
drive.
Full boot log with linux-libre 4.10 and libreboot 2016-09-07 after hibernation
attached.
Where can be root of issue? libreboot code, linux-libre code or GuixSD itself?
Regards,
Nikolay
