HDMI works different on last lot of RK3288

adamoa

I have several RK3288 units produced in 2015 that work perfectly with KODI. The last batch of cards produced in August 2018 used in the same equipment, give error "[drm: dw_hdmi_rockchip_set_property] * ERROR * failed to set rockchip hdmi connector property" in dmesg.
What has changed compared to previous lots? How can I solve the problem?
Thank you in advance for your answer.

I made some deeper analysis about the issue:
This is the crashlog file produced by kodi which better document the error:

Can you please help me solving this issue?

Thank you for your answer, I'll try changing the resolution depth to 24 or 32, if kodi permit it.

In the mean time, I discovered what is the difference between the old and new board: the GPU version.

Old board GPU:   Mali-T76x 4 cores r0p0 0x0750
New board GPU: Mali-T76x 4 cores r1p0 0x0750

The issue is up to Rockchip. Can you suggest any solution for that?
