Created attachment 1243163 [details] coredumpctl output I've been getting random crashes a couple of times per day with latest xorg.* mesa.* (since a around 2 weeks now) and don't really know where to put this report. Current situation: I've been running the latest Fedora 25 updates together with Xfce 4.x. The system is a Lenvo E325 Notebook with a Radeon HD graphics APU installed (APU E-450). The radeon driver is being used (iirc). An external Monitor is connected via VGA and usually is always turned on. Under unknown circumstances every now and then the entire xwindow system crashes (no reboot of the system, just crashing xwindow system), trashes all open and running programs, loading up lightdm after a while again so you can re-login. From that point on you can operate the system normally again. Sometimes ... when this happenes ... it's not possible to shutdown the Notebook anymore because once the xwindow system gets closed a picture with random artifact GPU memory content shows up and then locks up the entire Notebook. You need to press power-off to shut the Notebook down. The crashes aren't the problem, because it's always possible to recover from that crash and manually unmount critical drives. Sadly all work done by open programs (like spreadsheets, editors) etc. are totally lost. Please find attached a coredump output (text).

Created attachment 1243608 [details] full backtrace I was able to catch another coredump and created a full bt from it. Please find attached a full backtrace of the reported issue.
Looks like an driver issue within the ati driver package ? Tried re-assigning, hope it worked.
The issue is gone with recent kernel and mesa updates. Must've been a regression. If this issue shows up again, I will re-open a new bugreport.
