ColdFire 5329 cache problems.

ColdFire 5329, SDR SDRAM, boots from flash and runs with the cache disabled, boots from flash runs for a while and then hangs when cache is enabled.  Runs fine, cache or no, from the debugger.  The problem appears to be related to a part of the code which reads data from an FPGA across the flexbus, with that data then stored in a buffer in SDRAM.
