--- Comment #24 from jian-hong@endlessm.com --- Created attachment 139485 --> https://bugs.freedesktop.org/attachment.cgi?id=139485&action=edit dmesg of loading amdgpu module - tested in 4.17-rc4
I also tried Linux kernel 4.17-rc4 again. However, the system still hung up with the following error. The attachment is the full dmesg.
