Re: Kernel panic while compiling kernel

[Zachary Amsden <zamsden@cisco.com>]

Just an observation - I've noticed that several of the include files 
include linux/config.h and some include xeno/config.h - also for some 
other included files this is the case.  Also,  -nostdinc only seems to 
be applied to the arch/i386 branch - which means the drivers may be 
getting a different set of include paths.  Perhaps some of your config 
settings are different in different .c files as a result with 
non-standard config options.  Although I kind of doubt the problem is 
this simple, it seems reasonable to clean up the build tree so that it 
has a well isolated include structure.  I think I just volunteered 
myself unless anyone else is already working on it.
