It seems there's something different broken, all newly built
kernels are instantly rebooting. All are displaying the
"edd=off" warning message.

The gcc version is slightly different (4.1.3 vs. 4.3.3, both Debian),
but I'm already running next-20090306 compiled with this compiler.

Has anyone a clue on howto debug the build environment or
debugging the kernel before it's getting booted?

Nico
