[OT] Cisco 4.0.5 VPN client prints non-fatal stack

[OT] Cisco 4.0.5 VPN client prints non-fatal stack

[Alessandro Suardi]

...and works, as I'm currently connected via a 4.0.5 VPN tunnel.

VPN client 4.0.4.B works without printing the kernel messages.

Problem happens with 4.0.5 on both 2.6.8-rc3-bk4 and 2.6.8-rc4,
  didn't test earlier kernels.

Since I know Cisco people are reading this list, and in case
  someone else may be interested... I'm aware this may not be a
  Linux kernel problem at all, but just in case - h
ere it goes:

cisco_ipsec: module license 'Proprietary' taints kernel.
