It occures to me that I may have been testing kernel latency as the -17 version seemed worse than 13.10 had been. That is pulse->jackd bridge may have been running with jackd set to -p64 (2.67 ms as jackd reports) which is below the latency most Intel HDA setups are able to handle (-p128 is the normal lower limit). There were certainly xruns as this is at the edge of where things work with hyperthreading turned on. (hyperthreading off gives sub ms latency) All reboots since then have not had jackd started and still had kernel errors. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1294729 Title: BUG: pcmC1D0c:0, pos = 5461, buffer size = 5461, period size = 2730 Status in “linux” package in Ubuntu: Confirmed Bug description: Bug keeps showing up every 5 10 min or so.
