DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)

An attempt was made to access a pageable (or completely invalid) address at an

interrupt request level (IRQL) that is too high.  This is usually

caused by drivers using improper addresses.

If kernel debugger is available get stack backtrace.

Arguments:

Arg1: 0000001c, memory referenced

Arg2: 00000002, IRQL

Arg3: 00000001, value 0 = read operation, 1 = write operation
