artsd prevents CPU to enter ACPI power state C3


the artsd daemon prevents my Thinkpad T20 to enter the ACPI power state
C3 (most likely because bus master activity is not 0 at any time). Without
artsd the C3 state is entered successfully if the CPU is idle. I use
Linux 2.4.21 with latest APCI patches and ALSA 0.9.4.

Can someone explain this?
