[drm:drm_edid_block_valid] *ERROR* Raw EDID

[sam tygier]

With 2.6.25 and 2.6.26 kernels with KMS enabled i get completely blank screen after booting, the monitor turns off because there is no signal, and i can switch to a VT. i can however SSH in to the machine. also it boots fine with radeon.modeset=0

with previous kernels the monitor works fine, correct resolution is always detected.

i have
08:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3600 Series
and anEIZO S2242W monitor

i see lots of messages like:
radeon 0000:08:00.0: DVI-I-1: EDID block 1 invalid.
[drm:radeon_dvi_detect] *ERROR* DVI-I-1: probed a monitor but no|invalid EDID

in dmesg.

i have reportedhttps://bugs.launchpad.net/ubuntu/+source/linux/+bug/601376 which has some more debug info

a search leads me to a thread
[PATCH 1/2] drm/edid: Make EDID header fixup threshold configurable
http://thread.gmane.org/gmane.comp.video.dri.devel/45591
but i can't see if that patch has been merged, or if there is any follow up.

is there any news on this issue?

thanks
