[Bug 100753] [i915] [SKL] GPU HANG: ecode 9:0:0x86dffffd, in Xorg | Xwayland [4561], reason: Hang on render ring, action: reset

--- Comment #18 from Milamber <milamber at linux.com> ---
Another GPU Hang with these parameters in grub:

# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-4.9.0-2-amd64
root=UUID=1a7380f6-83de-4a8a-970f-7f61d9ace0ef ro i915.disable_power_well=0
i915.enable_psr=0 i915.enable_rc6=0 drm.debug=0x1e log_buf_len=1M quiet

Seems this issue is not related to RC6...?
