Could you elaborate what do you mean exactly "stop"? Fail to load or
initialize the driver, or silent output, DMA error...?

Sorry but don't know at what
point. Card is an isa CS4236. Glad to provide
any other info/testing.

Any relevant kernel messages are welcome. Also, if you passed any
(module) options for the sound driver, show it, too.

The biggest change in ISA sound driver codes between 2.6.24 and 2.6.25
is that we dropped the PnP resource re-configuration via module
options of sound drivers. They have to be adjusted via sysfs now (if really needed).

Otherwise, if it really worked on 2.6.24, we have a good chance to
identify the affecting changeset via bisect. There are only a few
changes for sound/isa.

For what it's worth and as a preliminary comment, snd-cs4236 is my main test driver and works fine for me.

Rene.
