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
