Dear Philipp,
I have a iMX6dl custom board with custom Linux Kernel 4.8. I have both LCD and HDMI connected to the board. And we are using weston/wayland as the display interface. In normal boot, both LCD and HDMI display is working fine.
But, currently, for one of our customer, I am trying to explore and support snapshot image booting on it. Currently, we are able to resume the system without display. Also, if we make the entire imx-drm as modules, and then install the modules are resume, even LCD is also coming up. But HDMI display is black out.
After, resume, when I try to launch the weston, I noticed the following errors: enabling vblank on crtc 0, ret: 0 [PINTU]: drm_vblank_get: CALLED: vblank->refcount: 1 ------------[ cut here ]------------ WARNING: at drivers/gpu/drm/drm_atomic_helper.c:1121 drm_atomic_helper_wait_for_vblanks+0x228/0x24c [drm_kms_helper]() [CRTC:24] vblank wait timed out .....

And, when I try to reboot the system, the system does not reboot. And I get the following error: /wayland # reboot .... [17:55:01.180] destroy output while page flip pending ... imx-ipuv3 2400000.ipu: DC stop timeout after 50 ms
If you have any clue about this issue, please let me know.
Any help will be really appreciated!
Thank You!
