I just totally (And I mean totally. Reformat the drive, reinstall the boot loader (which I don't think I had to do), installed last night's build, set up my preferences manually, saved a config file, and then upon loading the very first MP3 in my playlist (I created an m3u manually, not a playlist via rockbox) it played for about 5 seconds and then I got Data Abort at 00030F18. Rebooted, hit the playlist again, different song came up because it's on shuffle and then Data abort 00030F18 again.
3rd try, same thing. This appears reproducable 100%.
***EDIT*** Sorry, I'm on an iPod 5G 30gig.
***EDIT2** First song to play on the 11/13 build did NOT crash. So I'm going to leave it there for now.
