Created attachment 139536 [details] dmesg output from a failed attempt to load amdgpu I currently have an AMD 2400G with Integrated graphics that i am trying to get to a screen with amdgpu. At the moment, booting up to a VGA console works with amdgpu blacklisted. When attempting to modprobe amdgpu, the system hangs on the vga console and the display seems to stop updating. The underlying system seems unaffected, because blindly typing 'reboot' causes the system to reboot. Steps to reproduce: 1. Use kernel 4.17-rc4, compiled with the attached config. 2. Blacklist amdgpu in modprobe.conf.d (or else booting to ANY screen will fail) 3. modprobe amdgpu Expected result: -Successful driver load. Observed result: -See attached dmesg output. (It is worth noting that the dmesg attached also shows a nvidia gpu in the pci bus. This issue is not affected by its presence or absence. This issue has been tested both ways so far.)
