Hi Timo,

Sure. I ran the upstream test-suite on ppc64el and powerpc ports for
comparison, both running on KVM guests, linux kernel 3.14 (Debian).
git remote: git://sourceware.org/git/systemtap.git
git commit: 035685897c43de5cdbc15b3fc38d75c6a8955bc3
# ./configure [args from Debian srcpkg + --disable-refdocs]
# make -jN
# make install
# make check
# make installcheck
(following [1])
On powerpc:
# make check

I currently lack some more systemtap background to be sure.. but overall
835 uf/1078 ep vs. 244 uf/1692 ep doesn't look very good. Does that
match your opinion?
If that holds, I can try to look into the failures for clues (haven't
done that yet).
Thanks!
