Description of problem:
When playing audio with xmms, the audio will play fine for a while, and
then start skipping forward, making it unlistenable, and leaving entries
like this in /var/log/messages:

snd_pcm_avail() returned a value that is exceptionally large: 18446744073709544844 bytes (418293516372 ms).


Version-Release number of selected component (if applicable):
kernel-2.6.29.6-213.fc11.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Boot into kernel-2.6.29.6-213.fc11.x86_64
