[meta-ti] Kernel crash running omap3-sgx-modules_4.05.00.03 on 3.x kernels

[Kovesdi Gyorgy]

Hi,

I have Beagleboard-C4, kerner 3.2.28

At last i could compile libgles and sgx modules version 4.05.00.03 with some 
hacks, and found the following error running any gles-based application:

Previously i tried it on Angstrom with the same result. The kernel can be any 
3.x version, the result is also the same. It can run on 2.6 kernels only.

The calltrace is:
