Issues with Tun and OpenConnect/Anyconnect [SOLVED]

[Atmmac]

Everything was working fine previously on 3.10.7-gentoo-r1. I had to upgrade to 3.12.0 due to nvidia issues. Having problems with tun. I have it compiled as a module in my kernel and everything looks cool until i start anyconnect or openconnect and it hangs my system. I get the following with dmesg.

Any thoughts on this issue?

Thanks!

Updating to the 3.12.1 kernel solved this issue. I am marking this as SOLVED.
