A simple fix would be to replace vcpu_unimpl() with kvm_pr_unimpl() (also vcpu_debug_ratelimited() with kvm_debug_ratelimited() as well) in kvm_msr_ignored_check().

I did so: https://gitlab.freedesktop.org/drm/amd/-/issues/1354 However this morning I found suspend/resume doesn't work anymore with the old monitor. It worked with firmware in http://download.opensuse.org/update/tumbleweed/, but that's now gone and http://download.opensuse.org/tumbleweed/repo/oss/ is now used: 3400G:~ # zypper se -is kernel-firmware-amdgpu Loading repository data...

Libvirt was running but didn't respond to anything - "virsh capabilities", "virsh list --all" just froze. Please, take a look at the attached logs. After rebooting to previous Kernel, 5.8.15-1-default everything works fine, I don't see anything suspicious in journal.
