SubjectDRM edid logspam even with loading edid data from file
Hi,

I have a monitor connected via a KVM to a radeon card (ATI RV620 LE [Radeon HD 3450]),
since it's a server i previously used "nomodeset", however i just tried using
DRM/KMS but my logs get spammed with messages about invalid EDID.

I have tried to circumvent this by loading the edid data from file with
"drm_kms_helper.edid_firmware=edid/1680x1050.bin", that seems to work in
principle but the log spamming didn't stop:

.... endlessly

The message about VGA-2 eludes me .. since only the HDMI is wired up.

Is there any reason for it not to just take the edid-data from file and be done
with it .. instead of keep retrying stuff that will fail and log spam ?
