Hi Clemens (and everyone else),

This didn't fix the bug. See:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1191603

and:

https://bugs.launchpad.net/ubuntu/+source/linux-lowlatency/+bug/1185563

Do you have any thoughts? Is this a problem with alsa/jack (as seems to be
being implied) or with the kernel?
