Strange dmesg log message "Uhhuh. NMI received for unknown reason" on different Asus motherboards

    • Strange dmesg log message "Uhhuh. NMI received for unknown reason" on different Asus motherboards

      Hello,

      I am running the latest OMV 2.1 with kernel 3.16 (backports) on two different systems with Asus mainboards (P9X79 and P8P67 Pro, both with i7 CPUs). Both of them run several virtual machines using Virtualbox 5.0.10. I switched off most power settings for maximum performance. I had these messages already on older OMV releases (0.6, 1.0) and kernels (3.2) as well as older Virtualbox releases (4.3.x).

      Interestingly, I have another similar Asus motherboard (P8P67) running Ubuntu LTS, but I don't get these messages on that system.

      These messages pop up from time to time in dmesg and the console, although I am not experiencing any problems:

      1. [396864.035333] Uhhuh. NMI received for unknown reason 30 on CPU 7.
      2. [396864.035363] Do you have a strange power saving mode enabled?
      3. [396864.035383] Dazed and confused, but trying to continue
      4. [517312.723207] Uhhuh. NMI received for unknown reason 30 on CPU 0.

      Thank you

    • I wouldn't worry about it if it isn't causing any problems. The Debian kernels probably just have a different module/driver compiled in the kernel that causes it.
