I am afraid I can not help much. The patch you use is too old, I fixed
some bugs recently in the traps interception code which should lead to a
clear crash instead of some lockup. I also added support for VFP.

So, do you observe the same phenomenon with a vanilla 2.6.26 and the
latest patch (AFAIK Litekit is supported by mainline) ?

I also suspect a bug when using Xenomai with NO_HZ on ARM. So, you may
try to disable NO_HZ.
