    Dear Mike,
    
    
    Thank you very much for your answer. (Sorry for formatting my pastes as 
    citations. It’s because otherwise Mozilla Thunderbird will wrap around 
    the lines.

    I don’t have the command `omreport` installed.

    A newer firmware version is installed on my system.
    
    ```
    $ sudo dmidecode -t bios | grep Version
    	Version: 2.3.4
    ```

    So I guess you also don’t get the ACPI errors below?
    
    ```
    $ journalctl -k

    ```
    
    Does somebody have an idea? Might this be a regression in the firmware, 
    or the Linux kernel?
    
    
    Kind regards,
