Hello Yang,

I installed npcap-nmap-0.03-r6.exe but am still getting the IRQL_NOT_LESS_OR_EQUAL (a) BSoD on my Windows 8.1. system immediately when I start Wireshark.

I went back retested 0.03-r3, 0.03-r4 and 0.03-r5 to confirm that its only r5 and r6 that trigger the immediate BSoD on my system.  

Here's the last BSoD WinDbg output when using Npcap 0.03-r6.

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: 000000000000a620, memory referenced

Arg2: 0000000000000002, IRQL

Arg3: 0000000000000001, bitfield :

bit 0 : value 0 = read operation, 1 = write operation

bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)

Arg4: fffff8013ff660cc, address which referenced memory

Hi Jim, Pascal,

This IRQL_NOT_LESS_OR_EQUAL (a) BSoD seems to be caused by NdisAcquireSpinLock call in function NPF_StartUsingOpenInstance has referred to freed Open struct memory, I have tried to fix it in latest installer, you may try it at:

https://svn.nmap.org/nmap-exp/yang/NPcap-LWF/npcap-nmap-0.03-r6.exe

Cheers,

Yang
