推荐答案

KiFastSystemCallRet意味着该线程在syscall中-x86 NT syscall调度的一个不幸方面是它不会将上下文返回到原始位置，而是必须返回到ntdll中的静态位置，这将修复上下文并将您放回原处你从哪里来。粘贴到堆栈中，我们可以为您提供更多提示...

KiFastSystemCallRet means that the thread is in a syscall - an unfortunate aspect of x86 NT syscall dispatch is that it will not return the context back to the original place, but has to return to a static location in ntdll, which will fix up the context and put you back where you came from. Paste in the stacks and we can give you some more hints...
