The DHCSR (Debug Halting Control and Status Register) only as such gets
reset on a power on reset.
Are you sure you have executed 'cortex_m3 maskisr on' then issued a reset -
this will not change the interrupt mask - a power cycle will however.

we could change the behaviour to always reset this bit - depends on general
consensus.
