Hi,
What compiler do you use? I guess gcc 4.x?
There were issues with include/asm/system.h and gcc 4.x. As far as I
understood
- it is optimiser that doesn't remove "dead" code (which in its turn
would be activated if passed pointer in not properly aligned or points
to
correct data with allowed size). In my test kernel I just commented out
that
statement in the header. Frankly speaking, I have not tried to run a
kernel
compiled with gcc 4.x.

Seem to be having some
problem rebuilding the kernel from
source, doing this because of the ipv6 and the netfilter module issues!
I have this package
installed
kernel-smp-devel-2.6.11-1.1180axp_FC3
and I get this error

Thought I
would hit the list before I tried to confuse
myself intrying to decipher.
Thanks
