[SOLVED] suspend/hibernate not work on ThinkPad

hi!

I have a Lenovo Thinkpad X1 Carbon Gen 9.
I use wayland/niri as my window manager.
When trying to suspend with `systemctl suspend`, the keyboard backlight flickers for a short period of time, but nothing else happens.

journalctl --boot=-1 --grep="suspend"

cat /sys/power/state

freeze mem disk

cat /sys/power/mem_sleep

[s2idle]

systemd-inhibit --list

WHO    UID USER PID  COMM    WHAT  WHY                  MODE
UPower 0   root 3763 upowerd sleep Pause device polling delay

1 inhibitors listed.

How to debug this further? Looks like some resource blocks going to suspend, but I can't find any way to track this down.

[s2idle]

doesn't fit

Nov 07 17:12:39 thinkFu kernel: PM: suspend entry (deep)

journalctl --boot=-1 --grep="suspend"

Please don't grep.
But seems mhi-pci-generic 0000:08:00.0 is involved

lspci -tvnn

You could try to blacklist mhi-pci-generic

Re: [SOLVED] suspend/hibernate not work on ThinkPad

Thank you for that valuable hints!

I've checked the BIOS again and found some more power management features for Linux. Activating them, I have now "deep" as well.
Blacklisting "mhi-pci-generic" solves my problem! Currently, I have no use for the internal LTE modem, so Its ok to disable that kernel module.
