DPC_WATCHDOG_VIOLATION (133)
The DPC watchdog detected a prolonged run time at an IRQL of DISPATCH_LEVEL
or above.
Arguments:
Arg1: 0000000000000001, The system cumulatively spent an extended period of time at
DISPATCH_LEVEL or above.
Arg2: 0000000000001e00, The watchdog period (in ticks).
Arg3: fffff8047d71c340, cast to nt!DPC_WATCHDOG_GLOBAL_TRIAGE_BLOCK, which contains
additional information regarding the cumulative timeout
Arg4: 0000000000000000
