Rockbox

When playing back music on my iPod Nano (1st gen) with Rockbox (r14406), I have encountered situations where the playback breaks.

When this occurs, the songs often skip partway through, odd noises are played etc.

I have had this occur when listening to an album without touching the player at all (i.e. switch on, File browser, select track and play)

I find it can also happen if you press next/previous track quickly and repeatedly.

The problem is quite intermittent, sometimes it will play fine, other times you do the same thing and it will start glitching after a minute or two.
