vtsspp kernel module fails to load under Linux

Running "./insmod-sep3" as described in the instructions to build the driver fails:

Checking for PMU arbitration service (PAX) ... detected.
PAX service is accessible to all users.
Executing: insmod ./sep3_15-x32_64-3.11.10-25-desktopsmp.ko

Setting group ownership of devices to group "vtune" ... done.
Setting file permissions on devices to "666" ... done.
The sep3_15 driver has been successfully loaded.

Error:  vtsspp driver failed to load!

You may need to build vtsspp driver for your kernel.
Please see the vtsspp driver README for instructions.

dmesg gives the following output:

Manually running insmod-vtsspp in the sepdk/src/vtsspp directory gives the same error:

insmod: error inserting './vtsspp-x32_64-3.11.10-25-desktopsmp.ko': -1 Unknown symbol in module

I am running OpenSuse 13.1 with kernel version 3.11.10-25-desktop, installed V-Tune from vtune_amplifier_xe_2015_update1.tar.gz. Any idea on how to solve this?

(I tried googling for "__pcpu_unique_vtss_recovery_tskd", but got no results.

Hi Thomas:

First suggestion is to try upgrading to Update 2, released about two weeks ago.  Then, let us know if you still see the problem.
