/sys/class/drm/card0/error

X freezes in random time after boot.

Shortest record: 3 minute. Longest record: >3 hours.

It freezes about 10~20 seconds every time.

During freeze, the computer does not respond to any input, but the programs are
still running in background (e.g. games still runs in the background with
sound, movie are still playing).

After that, KDE will give a notification like "Desktop effect is reset since X
is reset" (something similar to that, I am using Chinese locale and therefore
cannot give exact words in English).

Some the words in the current window will be corrupted. This is most observable
in Firefox, many of the words in the current tab will be corrupted and become
unreadable. Refreshing the page doesn't help, but close and reopen Firefox will
make it returns to normal.

The freeze will occur only once per boot. After a freeze, the system will run
normally until the next boot.

Tried adding "i915.semaphores=1" in boot parameter and using UXA instead of SNA
(according to
https://wiki.archlinux.org/index.php/Intel_Graphics#X_freeze.2Fcrash_with_intel_driver),
but these didn't help.

Tried standard kernel of Arch and CK-patched kernel, both will give freezes.

Attached are dmesg, /sys/class/drm/card0/error, and Xorg.0.log
