While browsing with chrome, suddenly the computer didnt response for a few secs
then it returned to normal, found this in my kernel log:

[391718.800853] [drm] stuck on render ring
[391718.801631] [drm] GPU HANG: ecode 7:0:0x86d2fffd, in chrome [26527],
reason: Ring hung, action: reset
[391718.801632] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[391718.801633] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[391718.801634] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[391718.801634] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
