--- Comment #11 from Jani Nikula <jani.nikula at intel.com> ---
Reopening, I don't think we have conclusive evidence the problem is in
userspace, and even if the problem were in userspace, we'd need to identify
where in the stack and reassign.

qwang13, please elaborate on the issue. So do I understand correctly that:

1) The *external* DP/HDMI display works fine with all rotation options.

2) The *embedded* eDP goes black on some *external* DP/HDMI rotation options.

The attached logs are insufficient. Please add drm.debug=0xf module parameter,
probably also need log_buf_len=4M or similar because that debug option is going
to be verbose, reboot, reproduce, attach dmesg all the way from boot.
