            Bug ID: 102202
           Summary: "ERROR Requesting EDID firmware" (with amdgpu and EDID
                    file)
           Product: DRI
           Version: DRI git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: jb5sgc1n.nya@20mm.eu

I'm driving an LG 4k TV with an 4k HDMI signal from a RX 460 card, using the
amdgpu driver.=20

Since the TV is not always on when the computer is booted or woken up from =
S3
sleep, I dumped the TV's EDID to a file and use the kernel command line opt=
ion

drm_kms_helper.edid_firmware=3Dedid/LG_EG9609_edid.bin=20

to consistently let the driver know about the connected TV. In general, this
works fine, the EDID parsing provides the proper modes to be used.

But after every reboot, and also after waking from S3 sleep, sometimes also
triggered when using "xrandr" to change the video mode, I see scary kernel =
log
messages like this one:
