Created attachment 208701 [details] dmesg log after booting After a kernel upgrade from 4.4.3 to 4.4.5 (Arch x64), GUI failed to load as X server got hung up. Also, it prevent system shutdown/restart/hibernate and sleep (system just freezes, and there are too many errors related to video). Downgrading the kernel solves the issue, so the issue is defenitely with kernel itself.
