            Bug ID: 105156
           Summary: kdg2kfd_probe failed
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/amdkfd
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: sendion23-ux at yahoo.com

For some unknown reason, I started to get the "kgd2kfd_probe failed" message
after the update of Fedora-27 (limited to security advisories).  Here is dmesg
output:
  Console:  switching to colour frame buffer device 240x67
  radeon 0000:01:05.0: fb0: radeondrmfb frame buffer device
  kfd kfd: DID 9710 is missing in supported_devices
  kfd kfd: kgd2kfd_probe failed
  [drm] Initialized radeon  2.50.0 20080528 for 0000:01:05.0 on minor 0
from kernel version: 4.14.16-300.fc27.x86_64

Compare with the dmesg output:
  Console:  switching to colour frame buffer device 240x67
  radeon 0000:01:05.0: fb0: radeondrmfb frame buffer device
  [drm] Initialized radeon  2.50.0 20080528 for 0000:01:05.0 on minor 0
from the kernel version 4.13.9-300.fc27.x86_64



Q1. Is this failure expected?  Note that this system doesn't support IOMMU.
Q2. What to do if such failure is not expected?

  Thank you,
