Rockbox

Hi, I recently installed rockbox following the instructions online and using emcore (the flyspray howto says that 3rd party bootloaders are not supported, so forgive me if this is incorrect, but I thought it might be an exception since it was the official instructions).

Anyway, twice now, playback stops with a buzzing noise. The screen is visible but frozen and the ipod unresponsive. The only way to continue was to hold down menu and select until reboot (after which it was OK but had lost the playlist).

First time I assumed a bad mp3, but twice in two days seems unlikely. I am very new to Rockbox, so am unsure what else would be useful to report. The version number is r31516_120101. I am (more than) happy to install a more recent version if you point me to instructions. I can also provide more info if you explain what is needed. Unfortunately I didn't note the track(s) (but will try to next time it happens).

Thanks for all the work.
