[ 851.291557] Console: switching to mono frame buffer device 80x25 Otherwise known as wtf. Where did that come from and why didn't it switch back to the dummy device?
Can you please attach your Kernel's .config?

After run this case, the screen is black, connect it successfully via ssh, then run another igt cases, shows: No intel gpu found, run reboot, system is no response. It blocks testing.
Created attachment 107840 [details] [review] Possible fix Can you please apply this patch, retest and post the dmesg here? I tested this on BDW, and module_reload works for me on this machine, with this patch on top of drm-intel-nightly.

Maybe your system setup is wrong? This really looks like a bug in your machine setup, not our driver.

Execute commands below then run the tests, the result passes. apt-get install nfs-common nfs-kernel-server /etc/init.d/client_module mount -a root@x-bdw05:/GFX/Test/Intel_gpu_tools/intel-gpu-tools/tests# ./drv_module_reload unbinding /sys/class/vtconsole/vtcon1/: (M) frame buffer device module successfully unloaded module successfully loaded again root@x-bdw05:/GFX/Test/Intel_gpu_tools/intel-gpu-tools/tests# echo $? 0 [root@x-bsw01 tests]#./drv_module_reload unbinding /sys/class/vtconsole/vtcon1/: (M) frame buffer device module successfully unloaded module successfully loaded again [root@x-bsw01 tests]# echo $? 0
