Subject: Linux 3.6.11.2

Sorry for the late post. I wanted to send this from the Collab Summit,
but my connection home was unstable.

I'm announcing the release of the 3.6.11.2 kernel.

The updated 3.6.11.y git tree can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git v3.6-stable

The patch can be downloaded at:
https://www.kernel.org/pub/linux/kernel/projects/rt/3.6/stable/patch-3.6.11.2.xz

thanks,

-- Steve
