 Can you build a kernel with DDB_ONPANIC=0 or
 DDB_COMMANDONENTER="reboot" and try booting that, so that the system
 will reboot automatically once it gets to the cnopen panic?

 Just to check: did you disable amdgpu by booting a different kernel,
 or by entering userconf and disabling the amdgpu driver?  If you
 haven't tried the userconf approach, can you try that?
