You are right that the packages are not always in need of an update. I 
do believe something needs updated now that the headers have changed c++ 
compatibility, if I understood the comment someone made on this thread 
earlier. (or another recent thread with a similar problem)

Likewise, I only have one kernel header version which matches your 
version, only i386 instead of x86_64.

Running rpm -q --info kernel-headers describes the function the 
kernel-headers have. I guess only one version is needed and th headers 
are only updated with the kernel for additional features. The files are 
all under /usr/include/linux/... and don't seem to have version numbers 
for the headers.

Something seems amiss but I have no idea if a changed header file would 
cause it when you are not compiling anything

I doubt the kernel-headers would mess up your kernel installation either.

I guess the nash shell is used by initrd so being a shell, it probably 
interfaces the same way with the kernel from version to version. Maybe 
interpretation is handled differently in the newer kernel and nash works 
great for the working kernel but miserably . Other than guessing, I am 
clueless about the intricacies needed to load the intird correctly and 
to build it successfully, modprobe.conf and all the rest.

Mostly I'm supposing what may be happening and it is interesting to try 
t figure out what is going wrong with the latest kernel that was installed.

no problem with the time spent on trying to broaden ideas.
