modprobe lnet works, and so do the others (listed in the original strace), but we found

from dmesg:

This indicates you have mismatched ksyms at link, and are probably
linking against the wrong kernel modules.
Does this give more clues? Has anyone else run on a sles trace
kernel?
I think my trace packages work, but I have convoluted way of building
Lustre from a heavily modified spec in an rpmbuild based system.
The lustre autoconf and rpm scripts are clueless about non-default
kernel flavors. You need to specify everything kernel related to
prevent it from using default flavor bits. This is the relevant part of
how I do it from an rpm spec
%if %is_sles11
%define setup_flavor() \
krequires=$( echo $kversion | sed -e s/-%1// ); \
ksource=/usr/src/linux-$krequires; \
kobjdir=/usr/src/linux-obj/%_target_cpu/%1; \
kconfig=$kobjdir/.config; \
%eval_configure --with-linux=$ksource \
--with-linux-obj=$kobjdir \
--with-linux-config=$kconfig \
Make sure you have kernel-trace kernel-trace-base kernel-trace-devel and
kernel-source installed.
Hope that helps!
