It gives the Driver_irql_not_less_or_equal blue code. I found this thread from back in July and disabled "TCP Fast Open" and the immediate blue screens stopped. Just wanted to report that this is still an issue; I just recently started testing the AG Windows version again so I'm not sure if it's widely discussed or not. Is TCP Fast open ON a default edge flag (I don't recall enabling it)? Seems like an issue that's specific enough to warrant a disclaimer.
