You'd missing the 'make dep' step here.  Creating the dependencies is
important.

You might try saving the output from the 'make image' and 'make modules'
to see if iobuf.c gets compiled and linked into fs.o

The specific version shouldn't matter much, nor should the distro as long
as it supports S/390.
I'm not the one who built our systems here, but I'll ask.  I'd assume it
was the stock distro from SuSE.  Not sure about the timer patches, again
I'll ask, and in any case it wouldn't help with your module symbol
resolving problem.
