I upgraded from kernel 2.6.15-26.46 to 2.6.15-26.47 (both were dapper). Sound was working fine, now it is broken. I also use the snd_via82xx driver.

dmesg (after modprobe snd_via82xx):

There is a bug related to Nvidia (#60433) that says the boot_cpu_data symbol was changed in kernel 47. This seems to be the problem.
