Cisco AnyConnect causes OS X to kernel panic

crashkernel-panicsnow leopardvpn

My Macbook Pro 15" (Early 2011 – the one with Thunderbolt port) constantly kernel panics whenever Cisco AnyConnect establishes connection.

The panic tends to happen in the first ~30 seconds after connection is established.

The crash log is available here:

Any thoughts?

Some details:
Macbook Pro 15" i7 Early 2011 (the one with Thunderbolt)
Cisco AnyConnect version 2.5.2019

PS. I asked this question on the Apple Support forum, but so far I have got no answer 🙁

EDIT: This problem originally occurs in Snow Leopard, but problem persists in Lion (10.7), even after a fresh install (not upgrade from 10.6)

I've experienced the same issue on an iMac running OSX Lion (10.7.3). I submitted a bug report to Apple and tweeted at @anyconnect. You will need to work with Cisco support or use another version of the app unless we can narrow down the specific setting that is causing this crash.
