Hello.

I have Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio 
Accelerator] (rev 1).
xmms-1.2.5-pre1 worked fine with 2.4.4-ac11.
Sound support is compiled as modules.
After last kernel upgrade to 2.4.5-ac5 following problems occured.

1 xmms crashes with kernel message like "Unable to handle kernel NULL 
pointer ..." ( whole message in attached file )

2 Even executed immediately after module loading following happens
bash-2.04# rmmod cs46xx
cs46xx: Device or resource busy


cs46xx is loaded with cs_debuglevel=9
More information is in attached files.

PS: If additional information would be necessary mail me directly since 
i was not subscribed to linux-kernel.

-----------------
Good luck!
