--- Comment #1 from Elizabeth <elizabethx.de.la.torre.mena at intel.com> ---
Hello Filip,

If it's possible try with the last version of Kernel. 
Could you please attach the full dmesg log with the parameter "dmr.debug=0xe",
execute command:
sudo gedit /etc/default/grub
Modify the lines:
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="initcall_debug drm.debug=0xe"
Save the file, then update and reboot:
sudo update-grub
sudo reboot
Finally use the command “dmesg”.

About the error file, execute the command:
echo 0 >/sys/class/drm/card0/error
To empty the error state and try to replicate the bug again.

Thank you.
