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: https://gist.github.com/d947e73b0b6c17a863b7
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)
