Hi, I recently upgraded my system from 32-bit Ubuntu Edgy, with a custom hard-realtime-enabled 2.6.19 kernel, to 64-bit Ubuntu Feisty, with a hard-realtime-enabled 2.6.20 kernel. I also switched from an Athlon XP 2600 to an Athlon 64 X2 4600. In every way my new system should be faster, but jackd+usx2y worked on the last system, and doesn't work now. Here's what I'm doing to test the audio setup: ---------- sudo chrt -f 90 `pidof IRQ-23` # usb irq chrt -v -f 70 jackd -d alsa -dhw:1,2 -p 64 -n 2 # also tried defaults, and values up to -p 256 -n 8 chrt -v -f 25 zynaddsubfx ---------- After a short time (< 1 or 2 minutes) of switching instruments and playing notes with zynaddsubfx, all audio stops and jackd dies with the following error: ---------- ALSA: poll time out, polled for 7998858 usecs DRIVER NT: could not run driver cycle jack main caught signal 12 no message buffer overruns ---------- There is a corresponding message in the kernel log: ---------- [12546.132286] ALSA [...]/usx2yhwdeppcm.c:94: activ frame status -70. Most propably some hardware problem. ---------- I am loading the snd-usb-usx2y module with the nrpacks=1 option. I've gone through the HOWTOs I used to get things working on my last system (to some of which I have even contributed), and I am still having this problem. Does anybody have a solution, or do I need to take this to the developer list (since I plan to help fix this if anybody will point me in the right direction)?
