   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 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


No promises but it's a cheap experiment.

Good luck,
