thewade, Hi. I've had a few problems using ACPI at different times. When I first built my 2.6.9-mm4-VPS7 kernel I had ACPI turned on and had weird things happening. (Although not the exact one you are dealing with.) That said I am using the PlanetEdge kernel 2.6.8.1-1.520.2vS7.ll.rhfc2.ccrma at 128/2 with the HDSP 9652 and getting good results so far. Please remember to make your HDSP 9652 interrupt non-threaded. You might try booting and trying one or more of these options apm=off acpi=off pci=noacpi No promises but it's a cheap experiment. Good luck, Mark On Thu, 9 Dec 2004 19:36:37 -0700, thewade <pdman@xxxxxxxxxxxxxxxx> wrote: > Hello all, > > Im hoping that you can help me with a problem Im having > with jack and PD. > I am running jackd from qjackctl in realtime with a 64 > frame buffer (Hammerfall HDSP multiface: 2.67 ms delay). > I am using PD, and after both have been running fro about > 20 min I get a ton of xruns.
