https://bugzilla.kernel.org/show_bug.cgi?id=200531 --- Comment #4 from Aleksandr Mezin (mezin.alexander@xxxxxxxxx) --- After more testing: 1. "unable to handle kernel NULL pointer dereference" doesn't happen with 4.18-rc5 2. GUI/GPU driver still freezes at some point. Usually I need to leave the system turned on but with monitors in standby. Only "REG_WAIT timeout" errors in dmesg. 3. "REG_WAIT timeout" only happens with 2 monitors connected. Dell P2415Q and LG 27UD69P, both connected through DisplayPort How to reproduce "REG_WAIT timeout": 1) `xset dpms force off` 2) Wait for both monitors to turn off (backlight should turn off, "no signal" messages disappear) 3) "REG_WAIT timeout" will happen when you'll press a key/move the mouse - when the monitors are waking up (I've checked dmesg over SSH from another machine). -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
