Assertion: *** DPC watchdog timeout
    This is NOT a break in update time
    This is most likely a BUG in an ISR
    Perform a stack trace to find the culprit
    The period will be doubled on continuation
    Use gh to continue!!

PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced.  This cannot be protected by try-except,
it must be protected by a Probe.  Typically the address is just plain bad or it
is pointing at freed memory.
Arguments:
Arg1: deadbeef, memory referenced.
Arg2: 00000008, value 0 = read operation, 1 = write operation.
Arg3: deadbeef, If non-zero, the instruction address which referenced the bad memory
	address.
Arg4: 00000002, (reserved)
