Rob,
This is perhaps a silly question, but you had to change to the trace
kernel in grub, and Lustre is built against the kernel...
What kernel source/kernel headers are you using? My first guess is that
it's for the standard kernel, not the tracing kernel.

PS: dmesg sometimes has more details on these modprobe failures

Googled a slight bit and found no answer...
I've got a client node which I need to enable a trace-kernel in SLES11
SP3 + SMT updates.
I found that recent b2_5 client (from git) will build fine, but not
modprobe.
Same kernel without ftrace enabled works fine.
Enabled the trace kernel like this:
zypper in kernel-trace
after that's done edit /boot/grub/menu.lst and change the default to 0
to use the trace kernel
I git and build like this:
git clone git://git.whamcloud.com/fs/lustre-release.git
cd lustre-release
git branch --track b2_5 remotes/origin/b2_5
git checkout b2_5
sh autogen.sh
./configure --disable-server --disable-mpitests --enable-client
--disable-ldiskfs
make
make rpms
is this a known incompatibility?
below is as deep as I get today with debugging this....
Thanks... Rob
