Random system freeze on Sandy Bridge Mobile

I experience system freezes since kernel version 4.16. The freezes happen completely randomly usually within 2 days, and I can't even SSH into the computer after that, I have to do a reset. Once the freeze occur, the screen is either just freeze in the last state, or I can see a black screen with a thin green flashing line on the left side.

Workarounds that I found (no freeze at all):

  • Downgrade to Linux kernel version 4.15.
  • Completely disable acceleration (Option "NoAccel" "True" and Option "DRI" "False").

I tried also the followings, but doesn't work:

  • Disable just the DRI, but keep 2D acceleration.
  • Disable FBC (i915.enable_fbc=0).
  • Disable power management (intel_idle.max_cstate=1 i915.enable_dc=0).
  • Use modesetting DDX driver instead of intel.

System:

  • System architecture: x86_64
  • Kernel version: Linux 5.8.10
  • Linux distribution: Arch Linux
  • Machine model: ASUS X54C notebook
  • GPU: Intel(R) HD Graphics 3000 (SNB GT2)
  • dmesg log: i915.log
