Jack and Kernel Linux 3.5.0-33-lowlatency

[Alf Haakon Lund]

After the last update to Kernel Linux 3.5.0-33-lowlatency Qjackctl is 
reporting xruns even when idle (not playing or recording anything).

Reverting to Kernel Linux 3.5.0-31-lowlatency and there are no xruns. 
Where is the proper place to file a bug on this?

On a side note, I start understanding why people are freezing their 
systems once they get a working setup. If updates mess up you don't have 
a "production machine" anymore...
