This change has a DMCUB dependency - are you able to update your DMCUB version as well?

I can confirm this issue was gone after updating firmware.

❯ dmesg | grep DMUB
[   11.496679] [drm] Loading DMUB firmware via PSP: version=0x07002300
[   12.000314] [drm] DMUB hardware initialized: version=0x07002300


Mhm, that's a quite ugly problem.

The driver is supposed to work with older firmware as well or at leastissue a warning and provide a reasonable fallback.


How are we going to handle this?

Thanks,
Christian.
