TIMER_OR_DPC_INVALID (c7)
Kernel timer or DPC used incorrectly.
Arguments:
Arg1: 0000000000000005, Thread APC disable count was changed during timer DPC routine execution.
Arg2: fffff80002a196e8, Address of the DPC routine.
Arg3: 0000000000000000, Thread APC disable count before calling DPC routine.
Arg4: 000000000000ffff, Thread APC disable count after calling DPC routine.
The APC disable count is decremented each time a driver calls
KeEnterCriticalRegion, FsRtlEnterFileSystem, or acquires a mutex. The APC
disable count is incremented each time a driver calls KeLeaveCriticalRegion,
FsRtlExitFileSystem, or KeReleaseMutex.
