Jan 4 16:20:11 hummus kernel: ALSA sound/core/pcm_lib.c:155: Unexpected hw_pointer value (stream = 0, delta: -4095, max jitter = 8192): wrong interrupt acknowledge?

This is 2.6.1-rc1-bk4 with a :
ALSA sound/isa/cs423x/cs4231_lib.c:1056: cs4231: port = 0x534, id = 0xa
pnp: the driver 'opl3sa2' has been registered

Should I worry?

if you hear normal playback sounds, you don't have to worry too much
about this. it's a warning for the sloppy interrupts, and will be
disabled if you compile without CONFIG_SND_DEBUG.

Yep. The next kernel will have that :)
