    suspend/hibernate freezes Lenovo E480 22.04 5.15.0

    I know that this issue is very old and many time was solved, but nothing works persistent for me.

    Configuration:

    Code:
    /sys/power/state       
    freeze mem disk
    
    pm-utils package is installed

    and re-enabled policykit

    Code:
    [Re-enable hibernate by default in upower]
    Identity=unix-user:*
    Action=org.freedesktop.upower.hibernate
    ResultActive=yes
    
    [Re-enable hibernate by default in logind]
    Identity=unix-user:*
    Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.handle-hibernate-key;org.freedesktop.login1;org.freedesktop.login1.hibernate-multiple-sessions;org.freedesktop.login1.hibernate-ignore-inhibit
    ResultActive=yes
    
    [Enable hibernate to be run via cron]
    Identity=unix-user:*
    Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.hibernate-multiple-sessions
    ResultAny=yes
    ~               
    
    I can't debug what causes freezes since I have to hard reboot everytime. Any of these commands causes black screend and FN keys and power LED are still on.
    Tried uswsusp and hibernate packages. Same result.


    UPDATE: pm-utils suspend works fine, and I can turn on sleep mode in lightdm, but after KDE 5 starts any ACPI event: LID, PowerButton or sleep mode in KMenu freezes notebook.
