Halting mode debug presents a "debug illusion" to the user which looks like it does the right thing, but the steps to get there are not always exactly what the processor would do if there was no debugger. There are normally a lot of hacks done by the ICE logic around cache flushing to make sure the debugger does the right thing, for example.
Because of these background operations needed to maintain the illusion it tends to rather intolerant of misconfiguration of the MMU / TLB settings.
