I wanted to let everyone know that Andreas Herrmann of the Boeblingen lab
was able to help me with this problem. He did some diagnostic work, and
then contacted Ulrich Weigand to confirm that there was a gcc compiler bug
at work. The fix for the gcc-3.3 series is documented here:
http://gcc.gnu.org/ml/gcc-patches/2003-07/msg01153.html
for anyone that might run into the same problem.
After rebuilding gcc, I was able to get a working 2.6.5 kernel and modules.
Thanks to Andreas and Ulrich for figuring this out.

Subject: RE: make modules build error w/ 2.6.5
After specifying for 3270 support to be built in to the kernel, I got
further, but ran into yet another error. I did all sorts of google
searches, but didn't come up with anything that looked related.
I get through all the module compilations, and then into the "Building
modules, stage 2" phase. At that point, I see this:
Building modules, stage 2.
MODPOST
make[1]: *** [__modpost] Error 139
make: *** [modules] Error 2
If I turn on verbose messages with V=1, I don't reallys see anything more
meaningful. The command that is failing is this: make -rR -f
/mnt/hd/build-kernel-source-2.6.5-s390-1/usr/src/linux-2.6.5/scripts/Makefil
e.modpost scripts/modpost net/8021q/8021q.o net/ipv4/netfilter/arp_tables.o

more modules)
If I do a "dmesg" command, this shows up (worse than a kernel oops, since
the offsets are even more meaningless): User process fault: interruption
code 0x11 failing address: 40019000

So, apparently the modpost command is failing on me. I've tried recompiling
modpost with different compilers, and get the same results.
Has anyone else seen anything like this? The lack of hits from Google is a
little discouraging, to say the least.
