Same here with a XITEL MD-PORT AN1. mpg321 sits at around 5 % with kworker/0:1 at 95 %. Audio is choppy.

There's another report here: https://groups.google.com/group/beagleboard/browse_thread/thread/27de0f525a34c33b

Hacking and switching the config from DMA mode to PIO mode cuts the CPU usage to < 1 %. All good.

FWIW, `/boot/exlinux/extlinux.conf` is updated by u-boot-update. It looks like you can turn off automatic updating by adding `U_BOOT_UPDATE=false` to `/etc/default/u-boot`.
