Thanks a lot for all IRQ hints. Well, I disabled the nvidia driver and
ensured ALSA does not load the module for the internal AC '97 chip.
IRQ11 now looks as
11: 2428122 XT-PIC uhci_hcd:usb1, uhci_hcd:usb2, eth0,
yenta, yenta, ohci1394
Disabling the NIC is a no no, I really do not want to reboot for writing
an email ;-) .
Result: Better latency, so I can recommend to avoid IRQ sharing.
I can now run JACKD with -p128- This still gives some glitches every now
and then, *but* at -p256 as I used before the glitches seem to be gone.
I wonder if I could force the USB bus to another IRQ or if I could move
eth0 and yenta to another IRQ.
