This machine spams dmesg _very_ frequently with the following message:

ALSA sound/pci/via82xx.c:737: invalid via82xx_cur_ptr, using last
valid pointer

It doesn't happen constantly but comes in bursts. I haven't any idea
what triggers it since I can be playing 20 minutes without any messages
then there will be 50 of them with no change in computer usage.

It means that the driver reads an unexpected value from the CURR_COUNT
register to calculate the current DMA position. I'm also not sure
what's wrong. It happens only on a certain hardware.

You can turn off CONFIG_SND_DEBUG to shut them up.
