No xruns after disabling the ethernet interface. Kernel is the one
shipped in Suse. I think it is fair to compile just the realtime module
with the patch applied to source. I still have the capability module but
don't load it.
With the nvidia driver some xruns appear at -p64 -n4 but just in some
critical occasions.

Is this perchance built in to the motherboard? I'm having issues with an
athlon64 box on an asus a8v with one of these marvell gigabit nics built
in. This is with a digigram mixart 8 aes/ebu card. Jack is reporting
xruns fairly reliable when I switch windows in openbox.
I'll try disabling the nic tomorrow and see if that changes things at
all here.

Are you both using the same network driver/hardware? Does it share an
interrupt with the USB?
Ethernet controller: Broadcom Corporation BCM4401 100Base-T (rev 01)
Interrupt: pin A routed to IRQ 7
(b44 module, marked experimental since 2.4.x days)
USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M)
USB UHCI Controller
Interrupt: pin [A, B, C, d] routed to IRQ 11
This is an UHCI controller... I thought the usb kernel stuff was going
to get some attention, something about top-half/bottom-half irq
handling? Afaik that hasn't happened yet.
-ry
I'm in
Window$ now( developing in Flash, sigh!), can't check the irqs.
But I remember that I checked for this and the irqs were different.
It's also interesting that I got half the latency switching from
kernel-2.6.10 to 2.6.11. The latter is x86_64, BTW. And I can't get such
low latency on MacOSX or XP (neither with the Egosys PCI card). And this
is a USB card.
athlon 64 3200+ here. though at the moment the kernel is compiled with
CONFIG_MK7=y. I'll try MK8 tomorrow as well.
this is linux 2.6.12.3 on debian sarge.
