xruns after upgrade
After a major system upgrade I am getting xruns, when moving the mouse.
Question in short: is there an xrun problem known which is related to
* 32bit / 64bit software
* linux kernel 2.6.38 / 3.0.0
My environement until now:
ubuntu 11.4 32bit / normal ubuntu-kernel 2.6.38 (no rt, no lowlatency)
Focusrite Saffire 24 pro / FFADO-svn
jack-0.121 (-P70 -t200 -dfirewire -dhw:0 -r44100 -p128 -n4) (rtprio enabled in limits.conf)
ardour2.8.11 as well as ardour3-svn
This setup worked pretty well, xruns every now and then when changing jack connections.
Now I upgraded the system and thus changed to
ubuntu 11.10 64bit / kernel 3.0.0
and xruns coming up when moving the mouse, especially when the mousecursor is on the adrour window. The sound drops even a couple of seconds.
Both ardour2 and ardour3 are affected.
I tried the jackd1, that came with ubuntu, as well as a self compiled jackd1: same symptom. Changing the buffer size from 128 to 256 hides the problem, but I'd prefer solving it, if possible.
Thanks for your help
