You'd need to be outside X and at the main console to see it during a panic. Without that info I can only speculate this is related to something recently fixed in -current for AMD hosts. I suggest either trying a -current snapshot or building a custom 6.9-stable kernel with the patch supplied recently on bugs@: https://marc.info/?l=openbsd-bugs&m=162075185720480&w=2 -dv
