Logs from the kernel of the crash

Hi,

I am using xf86-video-intel 2.99.917-5 on archlinux and everytime my computer
comes back from hibernate (I go to hibernate using systemctl hibernate) the
intel driver seems to crash, but everything else seems to be loaded fine. So I
can't just see what's happening or something like that, because applications
running on xorg are up according to the logs.

I attached some logs of the errors in the logs.

In particular there is these errors in red:

[drm:check_crtc_state [i915]] *ERROR* mismatch in
adjusted_mode.flags(DRM_MODE_FLAG_PHSYNC) (expected 1, found 0)
[drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo
underrun on pch transcoder A
[drm:check_crtc_state [i915]] *ERROR* mismatch in has_pch_encoder (expected 1,
found 0)
[drm:check_crtc_state [i915]] *ERROR* mismatch in has_pch_encoder (expected 1,
found 0)
[drm:check_crtc_state [i915]] *ERROR* mismatch in has_pch_encoder (expected 1,
found 0)

Thanks,
