OMV 3.0.66 watchdog bug soft lockup..?

  • Hello!


    I recently put together my second server with OMV, this time I chose OMV 3. =)


    My problem is tho;


    NMI watchdog: BUG: soft lockup - CPU and then on all cores?


    Currently its running from a 16 GB usb 3 Samsung usbkey, which I am going to replace with an SSD. <- is this the problem or what can I do to fix it?


    Thanks!

    Can't read the screen but I would make sure you are using the 4.9 kernel. Is the usb key old? I haven't seen watchdog cause a problem when the usb key is failing but it is possible. If the stick is old, the OMV logging could cause it to start failing in a couple of days with the flashmemory plugin.

    The stick is brand new.


    Should I turn off logging?


    flashmemory plugin, I dont have it installed, should I?


    EDIT: I installed it, stupid of me to have missed that one. Remains to be seen if it will help my problem.

    I don't think installing flashmemory will fix the problem but it will prevent your usb stick from being written to death.

  • Late reply I know. But only upgraded recently, had the same issue.


    Kernel bug, related to Nouveau driver. Which manifests in cpu softlock and disk IO. Super strange.
    (note: my omv box is an all-in-one solution for me, which performs nas duties, as well as app server and cuda programming. That's why it has a Geforce graphics card although headless)


    Fix :
    > vi /etc/default/grub


    Edited the GRUB_CMDLINE_LINUX_DEFAULT line to this
    GRUB_CMDLINE_LINUX_DEFAULT="nomodeset".
    > update-grub



    Alternative fix : install latest nvidia driver.
