Thanks. Your new kernel log shows different crashes in the i915 kernel driver when using Wayland. In particular, the kernel driver seems to think the monitor has been unplugged/replugged:

[ 2.606884] drm_fb_helper_hotplug_event.part.38+0x97/0xc0 [drm_kms_helper]
[ 2.606887] drm_fb_helper_hotplug_event+0x1c/0x30 [drm_kms_helper]
[ 2.606903] intel_fbdev_output_poll_changed+0x6b/0xa0 [i915]
[ 2.606906] drm_kms_helper_hotplug_event+0x2a/0x40 [drm_kms_helper]
[ 2.606910] output_poll_execute+0x19a/0x1c0 [drm_kms_helper]

If you did not unplug/replug the monitor while the system was running then this sounds like a faulty cable or faulty connection. Please try a different cable and/or reconnecting the existing one more firmly.
