It works way better on my Panda ES, as with the 3.4 based kernel it's
freezing every time I stress the system (build a package, apt-get

Guess the old kernel had those issues with cpu_idle management for Panda ES.

Let us know when you had the new one on top of the latest stable
kernel snapshot, so we can try to get that one at Quantal asap.
