I have one older motherboard with an isa CM8330 sound chip which works
well under 2.4.x with isaPnP enabled, but I get this with 2.6.1:
Advanced Linux Sound Architecture Driver Version 0.9.7 (Thu Sep 25 19:16:36 2003 UTC).
pnp: Device 01:01.00 activated.
pnp: Device 01:01.03 activated.
bad: scheduling while atomic!
