I have a lenovo thinkpad S440 with this hardware:

$ lspci | grep "Display\|VGA"
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
06:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M] (rev ff)

i'm using ubuntu 15.04, but with the kernek 4.0.4.
i'm using Mesa 10.5.2

I use this to setup the PRIME:

xrandr --setprovideroffloadsink radeon Intel
xcompmgr &

and i start the warthunder game (closed source, bug free game) using this
DRI_PRIME=1 ./aces


All works fine, but after about 2 to 4 start game/exit cycles i usually have a crash that will lock the X, around the place where one should get the login screen.... here is the dmesg log:

Also, moving the game windows between screens just before the login screen make this lock, i assume it is also related to the crash above
