OK. The 'Unexpected pointer ...' messages seem to be related to IRQ threading,
so turning them off fixed that. I still get xruns when opening or closing
hydrogen or ardour. Also, ZynAddSubFX generates huge amounts of them.
Any ideas?
dmesg gives me this:

Hi all.
Does anyone have any ideas on what this message means:
Unexpected hw_pointer value [1] (stream = 0, delta: -106, max jitter =
128): wrong interrupt acknowledge?
It seems to accompany the xruns I get with the 2.6.9-rc2-mm4-VP-S7
kernel. Otherwise, this gives the best results I've yet got with jack.
Incidentally, has anyone ever had an xrun-free system with
jackd -R -d alsa -p64 ?
Hi
i saw these errors when my jack tmpdir was not mounted on a tmpfs mount.
The delays which this caused in the jack client caused errors like the
above.
