Black screen in x11 with amd rx 5700 xt in kernel 5.10.x

After starting x11 I get the following error in dmesg, and a black screen:

Building HEAD@3aaf0a27ffc29b19a62314edd684b9bc6346f9a8 5.11.0-rc6+ gives me the same result (black screen on displayport in x11) and reverting 4a3dea8932d3b1199680d2056dd91d31d94d70b7 gives me what looks to be perfect functionality.
