after some more test i am at this state: a xrun every few minutes but a big one (computer hangs for a second) in the moment i run my system without lounching X11 with no nvidia driver etc. so there is no irq sharing. i changed the irqproritys as described in the ffado-wik. so the question how can i find out what blocks the computer? the xrun is likely to happen when i start a programm like top or cpufreq-info can it be a problem with the new-firewire-stack? or is it just the case that the soundcard is not that good? because i have the same problem in osx. thank you all allready for the effort you have put into ffado! best olaf Stefan Richter schrieb: > sh0099 wrote: > >> Clemens Ladisch schrieb: >> >>> You can try to get separate IRQs by enabling MSI. >>> >>> For the FireWire driver, try this kernel patch: >>> http://git.kernel.org/?p=linux/kernel/git/ieee1394/linux1394-2.6.git;a=commitdiff;h=262444eecce40950af19ea4d75a3dc03b3c07283 >>> >> sounds interesting but i never compiled a kernel myself. >> do you think it is worth a try? >> do you have an idea where i will find a strep by step explanation >> > > https://help.ubuntu.com/community/Kernel/Compile > > >>> For the nvida driver, create a file /etc/modprobe.d/nvidia.conf with >>> this line: >>> >>> options nvidia NVreg_EnableMSI=1 >>> >>> >>> >> i think i should only do this after i patched the kernel, right? >> > > This is meant to work without patch with your present kernel.
