Linux Kernel 5.13.0-23 Suspend Modus

[Dietmar]

Hi there,

after updating to kernel 5.13.0-23 the suspend modus is not working anymore. I tried it with a Dell inspiron 5415 with AMD processor and a MacBook with a Intel processor.
I have to start with Kernel 5.13.0-22 and then it works fine.

When is suspend modus the computer doesn't wake up again.

Thanx in advance.
Dietmar

Thank you for the report and information! We're working to get a fix out. Please refer to bug 1956401 for updates

[Lukas Wiest (lukas-wiest)]

Bump this bug. Looking at the latest comments on bug 1956401 it seems someone should remove the duplicate mark here?

[Lukas Wiest (lukas-wiest)]

Ok, I've removed the duplication mark from this now and will continue to post my comments here, until someone responsible decides differently.

I tried to see something in the dmesg after a suspend attempt checking /var/log/kern.log
The only new line I could see compared to before the suspend attempt said:
"[ 389.117730] PM: suspend entry (deep)"
wich doesn't sound very suspicious to me, but expected?

Another line I spotted in the dmesg running on 5.13.0-27 on the other hand did:
"[ 1.238821] BUG: kernel NULL pointer dereference, address: 000000000000000c"
Booting with 5.13.0-22 or the current 5.16.3 mainline kernel doesn't have this.

Is there anything else you'd want me to try to capture from my system?
I'm using the tuxinvader mainline kernel ppa (ppa:tuxinvader/lts-mainline) on my focal installation in the meantime.

dmesg before suspend attempt

[Lukas Wiest (lukas-wiest)]

/var/log/kern.log after suspend attempt and hard reset after ~2 min nothing happened

[Lukas Wiest (lukas-wiest)]

Re-added duplicate mark, as on 5.13.0-28(5.13.0.28.31~20.04.15) suspend is working fine again.
