ASRock J3455-ITX Reboot Solution

  • Problem


    Hi to all owners of this "amazing" motherboard! After build my NAS on this motherboard and installed OMV 4 i I ran into the following problem:
    System reboots without any reason


    Dmesg and other log files are empty. After tons of forums i have understood, that there are 2 problems:
    - C-States of processor
    - Intel i915 driver


    Here is my output of
    root@openmediavault:~# last -x reboot

    Solution


    1. Go to UEFI/Bios and make some changes:
    - Advanced - CPU Configuration - Intel SpeedStep Technology - Enable
    - Advanced - CPU Configuration - CPU C - States Support - C1
    - Advanced - CPU Configuration - Enchaced Halt State - Disable


    2. Update kernel to latest aviable for Stretch d

    Code
    root@openmediavault:~# uname -r
    4.9.0-11-amd64





    3.1. Make changes in /etc/dafault/grub and change following line to:

    Code
    GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.modeset=1 i915.enable_rc6=0 i915.enable_fbc=1 i915.enable_guc_loading=1 i915.enable_guc_submission=1 i915.enable_huc=1 i915.enable_psr=1 i915.disable_power_well=0 i915.semaphores=1 i915.enable_execlists=0 processor.max_cstate=1 intel_idle.max_cstate=0"

    This black magic is working like a charm!


    3.2 Update GRUB configs and reboot


    Code
    $update-grub
    $reboot

    4. Enjoy your NAS without reboots!

  • did it depend to all Intel i915 chipsets? Or the only one on this board? Which one is on the Board? 915GV, 915GL, 915G, 915PL, 915P

    Equipment: a few Computers, lot's of waste heat, little time and a Pile of work.


    When solving problems, dig at the root instead of hacking at the leaves.

  • Many thanks!
    I had the same problem on the motherboard Gigabyte GA-N3160N-D3:
    Random kernel panic and rebooting. Regardless of OVM version and kernel version. Proxmox kernels also crashed.

    sorry for my english

  • I've been running an ASROCK motherboard for over two years now on a Ubuntu Fileserver, and I had this exact same problem, random reboots, mouse freezing up bad
    so my whole shell is frozen. Here is the reason after much headache and troubleshooting. Yes it is a hardware issue but something a bit more mundane than
    whats been posted so far. I had installed that file server on an M.2 memory stick (500 gig) on the motherboard and plugin itself, so I never used a PCI card adaptor.
    Turns out that if you have all your SATA ports maxed out which I did, there will be conflict with the M.2 channel simply because the M.2 channel on the chip
    will grab resources allocated to at least 2 sata ports. Of course I did not know any of this when buying this new technology, but regardless I had to share that
    because that was a real headache trying to troubleshoot the error source, when in reality it wasn't that complicated a fix actually..
    Of course my motherboard manual did not go into detail on the channel sharing priority off the M.2 interface.
