Hi

After installing Kernel 5.6 I am getting this error:

[ please send a personal CC, thank you! ]

Cannot run in framebuffer mode. Please specify busIDs for all
framebuffer devices

This used to work just fine, with Version 5.5, Gentoo/Funtoo Linux.

Very strange.

With Kernel 5.5 everything was fine:

this is what I get with Kernel 5.5

Kernel Config is attached.

Looking forward to any help or reply.

I went back to version 5.5 of the Kernel (recompiled after git
checkout v5.5) and all is fine again.

Best
