That's exactly what I am saying. It was a pre-release version of US I was playing with, but with the move from a Raring based to a Saucy development version the rt kernel had a broken video driver (radeon r600). If that driver is working in current rt kernels that issue may have come and gone, but the fact that it got out at all means that the rt patch set has broken drivers before and could do so again.
Since I edit video, the rt kernel is not needed for my normal workflow and is not installed in my normal operating system On 5/19/2014 at 6:17 AM, "Kaj Ailomaa" <[email protected]> wrote: > >On Sun, May 18, 2014, at 07:59 PM, [email protected] wrote: >> Watch out for rt-kernel issues with 3d desktops.
