Hi!
I have a BeagleBone Black with Debian Wheezy and want to cross-compile
the kernel (need some additional modules not in the default kernel).
So far, I succeeded compiling the kernel and running it on the BBB, but
then I get no HDMI output.
For building on my Debian Wheezy x86_64 I did:

If I then boot it, I see the new kernel beeing loaded, but when the
display is enabled, it fails. (system continues running, just no HDMI
display output); See the output on the debug serial:

Is this just a problem on my setup, or are the repos broken?
How could I fix that?
It's the first time for me to compile a kernel, so I'm unsure how to
proceed from here...
cheers,
