Xilinx board and NPTL support lockup

Hi Kevin,

This doesn't look like an NPTL problem to me. It appears you have 
rebuilt the kernel, and your new kernel has a problem booting on the 
board. I would check the configuration options you have enabled in the 
kernel, and I would check that xparameters.h (older kernel) or the 
device-tree (newer kernel) is right for your hardware design.

If you haven't rebuilt the kernel, then I would check your setup.
