https://bugzilla.kernel.org/show_bug.cgi?id=199425

--- Comment #5 from mikita.lipski@amd.com (mikita.lipski@amd.com) --- Created attachment 276171 --> https://bugzilla.kernel.org/attachment.cgi?id=276171&action=edit Patch to either dublicate or reuse an existing crtc state that might pervent use-after-free error in race condition

I wasn't able to reproduce the issue, but could you please try applying this patch and seeing if does any difference?

Also could add a dmesg log with drm.debug=0x6 to see whats the chain of events that caused the issue

Thanks
