Hi,

I'm also getting oops and freezes with the new rt-kernel. No
experimental mesa drivers now, but still I only get 3d accelerations
with the experimental mesa drivers. I also get some errors on startup
about nouveau driver (on both kernels) and a error about a USB device
file with the rt-kernel.

I was using supercollider, jack and ardour. The oops bug report is here:
