[Vpn-help] Bluescreen with 2.1.0-rc2

[Joerg de la Haye]

Hi list,

with 2.1.0-rc2 I get a bluescreen under certain reproduceable 
circumstances. The error message is "IRQL_not_less_or_Equal" in 
conjuction with ndis.sys, and I guess it has to do with the ndis-changes 
from rc2, as it didn't occur with earlier versions.

You can get the bluescreen if you access a CIFS/SMB share at some server 
by typing \\<servername or -IP>\<share> and start to browse some files. 
The bluescreen doesn't appear immediately, it appears 2-3 seconds after 
accessing the share and browsing files. Disabling the Shrew Soft 
Lightweight Filter let the bug disappear and you don't get the 
bluescreen, so the Lightweight Filter is very likely the cause of the 
bluescreen. At least it has to deal with it ;-). This happens without 
starting the VPN client itself at all, I haven't tested yet if it 
appears when you access the share via an client-established 
IPsec-connection. If you use other protocols like ssh, imap or smtp e.g. 
with enabled Lightweight Filter for that connection everything is fine.

My OS is Vista Business x64 SP1, and my network card is an onboard Intel 
  82566MM. The driver version of the NIC is 9.7.255.0, but I tested 
older and newer versions with the bluescreen appearing also. May I help 
with certain logs, dumps and tests? I haven't followed the usually 
desired bug reporting procedure as it happens without starting the VPN 
client itself at all.

Regards,
Joerg
