Hi,

i tried this test tree with omap2plus_defconfig.

it seems the kernel crashes and poweroff the board on loading this hdmi 
stuff, but dont print any crashlog. is there a way any backtraces will 
be printed?
output from serial console: http://paste.pocoo.org/show/354850/
kernel config (omap2plus_defconfig, added squashfs support, added 
support to include initramfs in kernel, build omapfb stuff statically 
into the kernel): http://paste.pocoo.org/show/354853/

i am using a own toolchain to crosscompile with gcc-4.5.2, binutils-2.21...
