在一个函数用NdisAllocateMemoryWithTag申请内存,出现如此错误！

我在一个函数中用 NdisAllocateMemoryWithTag申请内存！为什么出现蓝屏错误！

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is
caused by drivers that have corrupted the system pool.  Run the driver
verifier against any new (or suspect) drivers, and if that doesn't turn up
the culprit, then use gflags to enable special pool.
Arguments:
Arg1: 00000004, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: 805456f3, address which referenced memory

NdisAllocateMemoryWithTag要求中断级别不大于DISPATCH_LEVEL，否则会蓝屏。检查你调用时的中断级别，必要时可降低级别。

我想除了这个中断级别外，还有其他导致整个蓝屏错误的么？

暂时我还没想到其他的可能，内存耗尽是会返回错误的，不会蓝屏吧。

但是我

DbgPrint("        KeGetCurrentIrql = %d\r\n", KeGetCurrentIrql());
返回的是2
NdisAllocateMemoryWithTag 的IRQL <= DISPATCH_LEVEL 这样看来是没有错误的啊！

级别  dispatch_level =2 么？
