Trouble with 2.6 Kernel

[Glenn.G.Hart at us.westinghouse.com]

I am trying to get Linux PPC 2.6.17.1 up and running on a Xilinx Virtex-4
FX 12 FPGA.  Everything appears to proceed normally, but at the end of the
kernel initialization it gives me a scheduling while atomic error.  I have
found on the web others having this problem, but without a good solution.
Do I have something configured wrong or do I need a patch.  The output of
the kernel is shown below.

  Thanks,
  Glenn
