Package: jackd2 Version: 1.9.5~dfsg-19 Severity: normal
jackd starts and runs fine on my laptop, but after a suspend/resume cycle jackd sometimes gets stuck in an infinite loop, using 100% of one of the CPU cores. I would expect a couple of xruns or other audio glitches, but not this type of complete lockup. Steps to reproduce: 1. Run 'jackd -P70 -dalsa -p256 -n2 -r48000 -P' 2. Suspend the computer to RAM 3. Wake the computer back up The output looks like this: [...@innsmouth ~]$ jackd -P70 -d alsa -p256 -n2 -r48000 -P jackdmp 1.9.6 Copyright 2001-2005 Paul Davis and others.
