It's related to scatter/gather display. As a workaround, you can disable scatter/gather display by setting amd.sg_display=0 on the kernel command line in grub. It's fixed properly in: https://gitlab.freedesktop.org/agd5f/linux/-/commit/08da182175db4c7f80850354849d95f2670e8cd9 Which should land in Linus' tree this week. Alex
