Hello Ben,

please CC me, otherwise I might not see your message. The bug is very
clear, I boot my machine, the screen turns black as soon as the X server
is booted and the system does not ping anymore. I rebooted several times
before the bisect and the bug always hit me. For my taste the offending
commit is to large. So maybe I can split it in multiple smaller commits
and than debug it. However I'm currently out of the office, so maybe
tomorrow. If you do any progress on this, please CC me in order to avoid
duplicate effort.

Cheers,
        Thomas
