Hi,
I reinstalled my system and now got problems with jack.
I'm using a 2.6.31.12 kernel with RT patch.
Configured it like my old 2.6.27 RT kernel(which ran fine).
Is there anything new I have to keep an eye on?
I got xruns using both jack-118 and jack-1.9.5
Options that might be important:
PREEMT_RCU ON
GROUP CPU SCHEDULER ON
SLAB ON
CFG IO SCHEDULER
TICKLESS SYSTEM OFF
HIGH RESOLITION TIMER ON
SYMMETRIC MULTI PROCESSING ON
HPET TIMER ON
PREEMPTION MODE REAL-TIME
TIMER 1000HZ
CPU FREQUENCY SCALING OFF
/etc/security/limits.conf is configured:
@audio - rtprio 90
@audio - nice -5
@audio - memlock 50000
Thanks for the help!

Hello Christian,
I'm running this Kernel for months with good performace. If I rememer
right I had some performance problems with the group scheduler enabled.
I have a core2duo P8700 on an intel chipset. If you have a similar
system the attached config might be useful.
best regards,
Martin

Recent Jack (from 0.118) removes the -R option,
realtime is now the default and disabled with -r.
Depending on how you start Jack this may affect you.
I had a similar problem today with a qjackctl that
uses the new syntax and a Jack (0.116) that doesn't
understand it. Apparently there was no compatible
Jack available this morning. Where did you get 0.118 ?
Ciao,
