For anyone who, like me, missed most of the past month or two of
discussions, this is where Ingo's 2.6.x patches live:

Thanks to whoever posted the kernel-traffic link. I almost feel caught
up to reality now. 8-]

Uhhhmmm ... anyone know if I want this:

or this:

have more options been added to the /proc/ interface for voluntary

I've seen some mentions of configuring alsa with debugging info. Is
there a brief explanation somewhere of how to best help with weeding out
the 2.6.x latency problems?

To get the lowest latency you have to (echo 0 > /proc/irq/?/?/threaded)
where ? is the soundcard irq and the rtc irq.
eg echo 0 > /proc/irq/10/ICE1712/threaded
& echo 0 > /proc/irq/8/rtc/threaded
