Dear RT Folks,

I'm pleased to announce the 3.6.2-rt4 release. rt4 is just an update
to 3.6.2. The not announced 3.6.1-rt3 is an intermediate release with
a single change.

Changes since 3.6.1-rt2:

	* Remove the softirq noise printk

The delta patch against 3.6.1-rt2 is appended below and can be found here

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.6/incr/patch-3.6.1-rt2-rt3.patch.xz

The RT patch against 3.6.2 can be found here:

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.6/patch-3.6.2-rt4.patch.xz

The split quilt queue is available at:

I tried it. Just low-latency desktop, seems slighty of less jitter, than
mainline.
Unfortunately the problem of threadedirqs continue, they never worked on
my machine.
I saw someone discuss a possibility to run basic realtime without threaded
irqs, but the full patch required it.
Could you or anyone detail it? If you want any info, just say what.

Peace Be With You.

I've updated the repo of patches to have rt3 and rt4 on master branch.

In my fixes branch (now v3.6.2-rt4-fixes) there is only the cosmetic fix
of adding a subject to the power-use-generic-rwsem-on-rt.patch,
everything else is in the main tarballs.

There is a gregkh v3.6.3 release - the series applies onto that with
only a trivial patch refresh required to kgb-serial-hackaround.patch

In fact, quilt may not even bother to warn about it, but git-am will
stop and ask you to double check things.  If git-am still fails when
we get to v3.6.3-rt5, then I'll refresh it on the -fixes branch.
