Package: jackd1
Version: 1:0.118+svn4104-1
Severity: grave
Tags: upstream
Justification: renders package unusable
A routine update on 20110204 renders both JACK1 and JACK2 unable to run with
Realtime permissions thus rendering both unuseable for low-latency audio
operations. Updated was performed on 2 different systems running different
Kernels and outcome was the same:
