Sorry now I am facing problems again with the 7.0-RELEASE
and the HPS USB stack (I am not able to get the stock
kernel to work with interrupt read).

This works. However running pk2 and pk2cmd will result the system to
crash immediately.

All the 4 crashes are caused by this problem.
It used to run fine with the 7.0-Beta1/2/3 kernel and the HPS stack.

How should I attack this problem?
