There is a potential for the chip to lock up on a reset if a shared dma engine is in use. The (ugly) work around requires a reset process which uses a mailbox command to synchronize the independent channels prior to the reset to avoid the issue. Unfortunately, the timing windows required to ensure this workaround succeeds are very specific, meaning we can't release the cpu during the barrier.
