IRQL_NOT_LESS_OR_EQUAL (a)
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 a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 00000054, memory referenced
Arg2: 0000001c, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: 80501ff4, address which referenced memory
