Dear RT Folks,
I'm pleased to announce the 3.0-rt6 release.
Thanks, here's some feedback from a user of Planet CCRMA (running an
unreleased build of rt6 on x86_64 which I have not had a chance to test
yet). See below for some details...

From: Tracey Hytry
After a lot of work I've managed to install Feodra15 on one of the
machines...
just to be able to test the x86_64 version of the new builds.
Enclosed is info from just after boot.
I didn't have anything set up to test it, but there were no more errors
afterwards;
starting x and transferring some files via nfs.
You can pass this along to linux-rt-users if needed.
