            Bug ID: 106496
           Summary: Hung screen at modprobe amdgpu
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)

          Severity: normal
          Priority: medium

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.)
