    Question Strange messages about power saving mode

    My laptop is usually not on speaking terms with the charger, and my electrical service is unreliable, which means I often hibernate the system when I leave the workstation for any significant length of time. Since upgrading to Leap 15, I get these messages on all of my console windows after I wake up the system. Can anyone tell me what they mean? What does it mean for a power saving mode to be strange?

    kernel:[31464.331224] Uhhuh. NMI received for unknown reason 2c on CPU 0.

    kernel:[31464.331225] Do you have a strange power saving mode enabled?

    I've seen those messages at various times over the years on various installations. Mostly any more I only ever seen them in dmesg, because of a workaround:
    Code:
    /etc/sysctl.d/local.conf
    containing
    Code:
    kernel.printk = 3 4 1 3
    that keeps them off the vttys.

    What does your /proc/cmdline contain?

    It didn't work. I'm still getting the messages.

    Not really related but, “video=1600x900 resume=/dev/disk/by-id/ata-WDC_WD10JPVT-75A1YT0_WX31C1202237-part5 splash=silent quiet showopts” only needs to appear once: check the boot parameters, with YaST Boot Loader module …
