Two displayport (dp) monitors lead to system freeze from kernel > 6.6

Hello together
With Kernel 6.6 (LTS), currently on 6.6.54-2, my setup work well. Both Monitors are connected via DisplayPort on my Dock and the Dock is via USB-C (3.2) connected to my Notebook. With all higher Kernels, my system freezes. Last test was with Kernel 6.12.0-rc2-2-MANJARO. Is only one Monitor connected → No Problem. As soon as the second monitor is connected, my system freezes.
Are both Monitors while boot connected, the login screen doesn’t shows up.

Hardware:
TUXEDO Pulse 14 Gen3
AMD Ryzen 7 7840HS w/ Radeon 780M Graphics
TUXEDO Triple Dock Lite v2 (C31TRIPLEDOCKPDPR02)
2 external HP Z27n G2 Monitors.
Both Monitors are connected via DisplayPort Cable. My Notebook is connected with USB-C on the Dock.

Is there anything I could reconfigure or is it a bug, when it’s a bug to whom can I report it?

Best regards
dasBaum

there is this report
Kernel 6.9 amdgpu crash with multiple monitors via MST: NULL pointer dereference (#3405) · Issues · drm / amd · GitLab

it is solved ( 2 patchs coming in drm-next )

How did you get the drivers to install? Were there issues during the build? I can’t even get that far.

I can only test it next tuesday
