With latest changes to kms code, my rs485 doesnt boot anymore (same build process, .config, etc. if i revert to rc2 it works fine, stalls with rc3,rc4,rc5. doesnt dump anything, no oops or panics, after the grub screen it starts loading the kernel and stops after the kms radeon load. sometimes it changes the LVDS to black after the kms radeon load (not all times).
Does the fix in this bug help? http://bugzilla.kernel.org/show_bug.cgi?id=13881
its working with latest rc5
