  • This is a kernel process. Has to do with ACPI and your bios.


    Is this the first time you installed OMV on this system?


    You can try several things and I would try them in this order:
    - upgrade to the backports 3.2 kernel
    - upgrade your bios
    - disable acpi in your bios (auto fan control)
    - update-rc.d -f acpi-support remove
