Why not just using Google?

According to http://www.raspberrypi.org/phpBB3/viewtopic.php?f=72&t=28379

Add the following line in /boot/config.txt
enable_l2cache=0
I believe that will disable your L2 cache for you. If not try =1.
enable_l2cache: enable arm access to GPU's L2 cache. Needs corresponding L2 enabled kernel. Default 0.

(I do not have a Raspberry board, never tried that myself, no warranty)

Can you help with this problem?
