Is this a regression? Was any earlier kernel version OK on that machine? If so, which version(s)? Thanks.
You are right, the LVDS spread spectrum code causes the boot delay. Starting with 2.6.33 I also get heavy image corruption - it starts with horizontal stripes and after some time / supend resume the image is completely disturbed. 2.6.31 - edid error 2.6.32 to .5 - boot delay 2.6.33 - boot delay + image corruption
