Dear Arne:
One of the things that I would do would be to carefully compare the boot
messages from the original functioning kernel with the newly compiled on to
see what differences there may be.
Another would be to contact your vendor and see if you can get the .config
for the original kernel compile and use that for your newly compiled kernel.
