[alsa-devel] interesting message, but not sure where its coming from

I'm working on a complicated program that uses the ALSA library in an embedded environment. I have things working pretty well, although occasionally I get the following message printed on the console:

buffer empty, loop_cnt 4727, loop_cnt_of_last_copy 4682, last period elapsed 4700, elapsed flag 0, chip_data->prev_cnt F000

buffer empty, loop_cnt 4758, loop_cnt_of_last_copy 4727, last period elapsed 4700, elapsed flag 0, chip_data->prev_cnt F000

I know this isn't my code, and I can't find anything that looks like this in the alsa library or the kernel. Does anybody recognize this?
