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: 666d12ce, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: 80532d52, address which referenced memory

If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: 666d12ce, memory referenced

Arg4: 80532d52, address which referenced memory
windbg已经清楚地告诉你了：在高IRQL时（IRQL值不小于2即dispatch_level)试图访问分页内存（或完全无效）
后面是参数：要访问的地址：666d12ce，当前IRQL：2 Arg3: 00000000即在read操作时发生的。。。
仔细看看WINDBG的输出还有多看WDK/DDK的文档
