Hi. I recently patched my kernel with the RP patch by Ingo to get rid of the many xruns I was getting with my brand new Multiface (PCI). THe result is somewhat strange, so I thought I'd post a summary here and see if someone else has had similar problems: 1. jackd -d alsa -dhw:1 -p64 At 48kHz, jackd ran the whole night with SuperCollider connected to some of its ports without a single xrun! This is a massive improvement. 2. jackd -d alsa -dhw:1 -p64 -r96000 This used to work without the RP patch applied, it generated some xruns, but it used to work. Now, using the RP patch, jackd seem to simply hang. If I boot up the SuperCollider synthesis server, it results in a "failed to start" message by SC. Normal jack clients like jack_lsp do still work, but jackd exits after about 10 seconds or so, claiming its watchdog killed it. Without -R, it runs without dying, but no audio clients work. One indication that the problem is really originating from within jackd is the fact that -v does not produce any of the load-statistic output if used as argument to jackd.
