Description Chris Murphy 2017-03-29 19:22:36 UTC 
Hardware:
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics 
Intel(R) Core(TM) i7-2820QM CPU @ 2.30GHz

Software:
4.11.0-0.rc3.git0.2.fc26.x86_64
xorg-x11-drv-intel-2.99.917-28.20160929.fc26.x86_64


NOTE: This laptop also has 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] (rev ff) but it is disabled in early boot by switcheroo-control to use i915 graphics. Therefore this is a GNOME on Xorg, not Wayland, session.


Problem: screen flickering, often Xorg crashes including all of user space


100% reproducible in a particular application: Red Hat Anaconda (installer), and only when at the installation UI which has a spinner and a status bar. If I'm anywhere else, so far I haven't seen the problem. And once the installation is finished, same screen but without the spinner or status bar (since the install is done), the problem doesn't happen either.

dmesg drm snippet

This is what was recorded at the time of the first flicker to black. There are some boots that are not black but have very scrambled video.

journalctl full output with drm.debug=0xe

To correlate kernel messages with user space errors. Output is monotonic time.

dmesg drm.debug=0xe (take2)

Original was missing a ton of info due to too small buffer. Used 'journalctl -b -k -o short-monotonic' to get just the kernel messages.
