 Wade,

are you sure that you did not build your hardware with evaluation cores of
the licenses? If you are using the evaluation licenses the hardware (FPGA
design) will stop working after a certain amount of time and you will see a
lock-up.

Good question.  How long before lockup?  The only core that should be
licensed is the ethernet, and I know it was sysgened on a system with a
license.  This is the Xilinx reference design for the ml403 board.

When we were using the eval version of Xilinx's 10/100 EMAC it would time-
out after 8 hours (and the kernel would panic since our root fs was NFS-
mounted).

If your only [to-be-]licensed core is Ethernet, then I take it you're using
the UARTLite, or a non-Xilinx UART?  We used Xilinx's 16550-compatible UART,
which is licensed, but I never ran with the eval version of that IP block
and so have no idea how long it will function before shutting down.
