	HELP PLEASE !!!

	I have built two machines, one system uses 32016/32082, plus fpu. The
other system uses 32032/32082 and has an identical set of peripherals and
memory. The 32 bit system runs at about 8Mhz and is a wire wrap prototype. I
have written a multiuser kernel in assembler which run perfectly on the 16 bit
machine. However when ported to the 32 bit machine it works only 90%, crashing
at regular intervals for no obvious reason. I have no ISE tools for the 32 bit
system so debugging is proving really difficult.
	If anybody out there has had problems with this combination of chips,
particularly using the MMU, I could do with some advice. The 32032 is a 
revision F part, the MMU a revision L, both are 10Mhz parts.

	Thanks in an advance, Phil.
