Subject: Failed to do bolted mapping IO memory with minimal .config

From: Olaf Hering <[email-masked]>
Date: Wed, 10 May 2006 11:59:43 +0200

The attached minimal .config fails to boot on a p620. With SLES10 2.6.16
it doesnt print anything past the pc: pointer (which points to out_8),
with current Linus tree it fails like shown below. Of course if works
fine with a full .config, but none of the offered and disabled options
seem to make sense for this system, so I left it disabled.
