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
3.1. Make changes in /etc/dafault/grub and change following line to:
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
4. Enjoy your NAS without reboots!
