Bug Description

Binary package hint: jackd2

jackd locked up (100% cpu) after wake from sleep. It unlocked periodically (approx. every minute) for a few seconds. In Ubuntu 10.04 jackd stopped when the laptop was put in sleep mode but this seems to not be the case for 10.10.

Extract from log after manually killing from console (first few lines repeated hundreds of times):
