@kugel:  I know you think we should abandon the 31/32 MHz PCLK rates but I think you should reconsider.  With the DBOP fifo patch(yours) the ui responsiveness is very good at 31 MHz.

Have you done battery benches or current messurements? I'm not sure 3x vs 6x makes much difference.

Also, we most definitely need to boost more often with 31MHz, which may result in higher drain again (since the main clock is at 248MHz then).

No benches yet, I just thought your main concern was ui responsiveness which your version of the DBOP fifo patch vastly improves for me at least.  I do seem to remember noticing that the higher PCLK setting did impact battery time when funman ran his benches a few weeks ago.  I don't have enough info to say that I think we should lower it, I'm just saying that ui responsiveness is not a problem at the lower frequency now as far as I can tell.

matsch:
Clipv1 r21190 sporadically stops playing MP3s showing 'filename (root) 1018'.
I think this happens more often when playing large mp3-Files or pressing pause play button several times for one file. Only after reboot the Clip plays again.

funman:
Yeah playback sometimes stops on the Clip.

The problem is known, and specific to the Clip, but no cause has been determined yet.

EDIT: If some people have a m200v4, it would be very helpful to tell if you meet this same bug, so we could relate it to the small amount of memory of these 2 models (2MB)
