what toolchain are you using? I'm using gcc-4.4-arm-linux-gnueabi
emdebian toolchain and got an ICE when trying to "make modules" on the
"merge" branch. It seems to be this error:
https://bugs.launchpad.net/gcc-linaro/+bug/623945 but turning off
CONFIG_DEBUG_INFO_REDUCED was a workaround that made the whole thing
cross-compile (in case someone else is running into it).

It boots and loads my rootfs just fine but the display is remaining dark.
But my dm and Xorg and e17 are starting properly, the processes are
running and I can't see any errors in the logs.
When using a strong flashlight I can see the display content so I guess
it's a problem with the backlight?
Before X is starting the boot logo (the penguin) show up properly.
The backlight was working properly with david's 3.1 kernel - is it
working for you?
In the log I see messages like:
[ 391.415924] td028ttec1_panel_suspend()
[ 391.437957] gta04_disable_lcd()
[ 395.173248] td028ttec1_panel_resume()
But it remains black.
Thanks for your efforts!
