Does not switch to suspend mode

Support

Good day.
I’m sorry for my English.
The computer does not switch to suspend mode. I read forums, tried to diagnose the problem.

journalctl --boot 0 --dmesg

how can I fix this problem?

I worked around this by disabling wifi. Might not be an option for most but since I’m connected with ethernet I was able to blacklist the ath12k module.

Here are the contents of my /etc/modprobe.d/blacklist.conf file:

blacklist ath12k
install ath12k /bin/true

After applying that and rebooting, running systemctl sleep worked.

There’s a bugzilla issue open for this:
