I tried this on a AMD system running an i386 kernel. I get the same bad
behavior.  This is from a 2.6.24-rc3 kernel downloaded from kernel.org.
I ran "make mrproper" followed by "make oldconfig" and accepted all the
defaults for the config.

There is one slight change with this experiment.  Other nodes are not
getting corrupted, i.e., uname -r is getting the correct value.
