            Bug ID: 199621
           Summary: iMac 2009, Mobility Radeon HD 4670: black screen on
                    boot
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.15.0-20
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)

          Reporter: floe@butterbrot.org
        Regression: No

I'm running Ubuntu 18.04 on a old-ish iMac from 2009. As soon as the kernel
modesetting kicks in, I only get a black screen. This is not a duplicate of
https://bugzilla.kernel.org/show_bug.cgi?id=100301 - if I try to enable the
screen via sysfs or xrandr, I get the following oops in dmesg:
