Slight side issue, while you guys are on the subject.
I have my soundcard (an onboard i8x0) sharing an interrupt (IRQ 11) with eth0
and usb-uhci. Would this be likely to give rise to xruns in a similar way?
I'd kind of resigned myself to this situation until such time as I upgrade my
hardware. Could any of the things you're discussing be applied to move eth0
and usb-uhci to a lower priority, or is it just a question of physically
moving the ethernet card? It seems like some dumb corner cutting exercise, as
the box was clearly only ever intended for office use.
If you find this problem remotely interesting, I'd value any suggestions.
