 Hi Taylor,
 
 You mean rebooting from ddb? I did the steps rebooting from ddb and no new =
 panic or error messages in dmesg. In fact, one of my AMD machines cannot ev=
 en get any input from keyboard when the system get the cnopen crash, in thi=
 s case I power off and on again. The other still can get input from keyboar=
 d and I type reboot in ddb, but no new message in dmesg at next boot with a=
 mdgpu disabled.
