A bisect points at commit 04f482faf50535229a5a5c8d629cf963899f857c for the
first bad one.  Unfortunately, I have not made netconsole work yet and the
hang is happening mostly right when X starts so I can't even see the console.
I will keep at the netconsole and see if I can get it functioning, also I will
try to boot this kernel in a VM and see if that helps.
