dmesg dump

using drm-tip from yesterday and latest bios (1.2.19) hotplugging a Panasonic projector fails, dmesg shows "EDID is invalid" but it works on a BDR laptop just fine.

another thing I noticed is that running 'xrandr --auto' does nothing with drm-tip, while it allowed the projector to be used with previous kernels

couldn't reproduce the next day..
