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: fffffffc, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: f79270a7, address which referenced memory

本来就运行在DISPATCH_LEVEL 级别的例程你加#pragma code_seg()还是在DISPATCH_LEVEL 级别运行啊。

加#pragma code_seg() 防止使用分页内存 导致蓝屏 目前蓝屏原因尚未找到 尝试降低IRQL等级不知道可行不

好像是 遍历EPROCESS链表的时候 会访问到 分页内存导致了蓝屏
我的猜想不知道是否正确
我想在EPROCESS的链表中遍历进程 是不是就不可以在 内核定时器中进行了
哪位高手写过 给点意见

不知道是不是I/O例程切换进程 引起的 (如果是 引起原因是什么 不清楚) 是不是要上自旋锁呢 高人给点意见吧
