Created attachment 83753 [details] error state xf86-video-intel-2.21.14 xorg-x11-7.4 xorg-server-1.14.2 x86_64 3.10.5 (been happening since 3.8ish) dunno the chipset, but comes from a Lenovo T520 (no nvidia in it, intel only) Gentoo Might be related to bug #67092 Here is how I reproduce it. 1. switch to external displays via xrandr 2. go about my day (play videos, go to websites, whatever) and switch back to the LVDS display 3. suspend 4. unsuspend and go to websites (heavy ones do this more, google plus, google maps, youtube sometimes as well). 5. hang/lockup I have NOT been able to get the error state stuff from a locked up system, only if it recovers (which it does 80-90% of the time I think).

Yes, the hang is #67092 and I would say the hard lock is #62373. *** This bug has been marked as a duplicate of bug 67092 ***
