            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. 

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 option

drm_kms_helper.edid_firmware=edid/LG_EG9609_edid.bin 

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:

*ERROR* Requesting EDID firmware "edid/LG_EG9609_edid.bin" failed (err=-112)

This would not bother me if only those messages were occuring, but I also
experience complete system lockups when I leave the computer display on (with
"xlock" running) and switch off the TV - these crashes seem to occur at the
time the screen blanker deactivates the monitor, but they leave no messages at
all in any logs I could cite. I've got the suspicion that both symptoms are
related (and maybe also related to
https://bugs.freedesktop.org/show_bug.cgi?id=100375 )

I am currently using
https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next as my
kernel, but experienced the same error also with previous kernel versions (like
4.12)
