Please try the simple change I proposed in my email. It's a 4 or 5 lines change max to your clock_toggle function and how it's called in send and receive. It should be trivial to check if things still "seem to work" to begin with. Do you have some kind of test mechanism that hammers the FSI continuously ? Such as doing a series of putmemproc/getmemproc & checking the values ? Then you can run that while hammering the LPC bus and generally putting the BMC under load and you'll quickly see if it's reliable or not.
