OT - Regression: Cisco VPN module hangs 2.6.30-rcX

[Fabio Comolli <fabio.comolli@gmail.com>]

Hi all.
Please forgive me if this question is considered offtopic on this
list. I'm not sure where to post it.

Anyway, I have a regression between 2.6.30-rcX and every other version
I tried with regards to Cisco proprietary cisco_ipsec.ko module.

The module compiles cleanly, loads and the VPN connection is created.
So far so good. The problem is that as soon as I send packets on the
tunnel (TCP - UDP doesn't matter, even a nslookup quesry i enough),
the system hangs without messages on console / logs. Powercycle is
needed.

Tested with 2.6.30-rc1 and 2.6.30-rc3 with same results. Last good
version is 2.6.29.2 . Arch is x86 without SMP.

The client version is the latest available to my knowledge,
vpnclient-linux-x86_64-4.8.02.0030-k9.tar.gz .

I don't know how to debug this, maybe some people from Cisco on this
list can help.

Thanks and regards,
Fabio
