Bug 32504

Description of problem:

Whatever is the mean used to hibernate, wake up never happens :

 - "rtcwake -m disk -s 60" doesn't work
 - "echo `date '+%s' -d '+ 1 minute'` > /sys/class/rtc/rtc0/wakealarm"
   followed by "systemctl hibernate (or Hibernate Button pushed)" doesn't work
 - "systemctl hibernate" followed by a keystroke on usb keyboard doesn't work

Though everything seems to be OK such as :

cat /sys/power/disk
[platform] shutdown reboot suspend test_resume

cat /sys/power/state
freeze mem disk

Hibernate itself works : system shutdown and when I push the Power On button, the environment is restored as it was before hibernation.
Only Wake up is failing.

More, the following actions are run without any issue :

 - rtcwake -m mem -s 60 does work
 - systemctl suspend followed by a keystroke on usb keyboard does work

By the way wake up from hibernate works also on Mageia-8 / kernel 5.15.126-desktop-1.mga8 and ubuntu 22.04 / kernel 5.15.0-88-generic

It seems that a similar bug was mentioned in this following recent email :

https://lore.kernel.org/all/CAJZ5v0iLCsiPncA1t7ogtpch9gjGjzjtDU6G5E+PHB8ZCHgY0A@mail.gmail.com/T/

... but was not recorded in bugzilla. I assume the patch proposed here has for target a recent kernel version with regards the date of the email.

Version-Release number of selected component :

Mageia-9  / kernel-desktop-6.4.16-3.

How reproducible:

 - "rtcwake -m disk -s 60" or
 - "echo `date '+%s' -d '+ 1 minute'` > /sys/class/rtc/rtc0/wakealarm"
   followed by "systemctl hibernate (or Hibernate Button pushed)" or
 - "systemctl hibernate" followed by a keystroke on usb keyboard
