This was actually on Elementary OS, but I've tried with a 4.2 kernel where the problem does not exist.
I've now also tries 4.12.0-041200rc1 and this input hang does not occur. Booting with this kernel does render my WiFi inoperable, though. I suppose that might happen when trying non-offical kernels, right? ** Tags added: kernel-fixed-upstream -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1689651 Title: vblank wait timed out on crtc 0 after screen lock on Dell Latitude e6220 Status in linux package in Ubuntu: Incomplete Bug description: After a screen lock, the screen hangs, with the attached stack dump in dmesg.
