I'm using r23198-091015 on my 8GB Nano 2G. I've noticed that if I enable Directory Cache (General -> Disk -> Directory Cache -> Yes) and Auto Update (General -> Database -> Auto Update -> Yes), once Rockbox restarts after adding new music files in disk mode, I always get a
*PANIC*
Stkov dircache
message. I then hold Menu and Select to reboot and the new files have been added correctly to the database, but clearly something is going wrong during the auto update.
Not sure if Flyspray is the correct place for this since Nano2G is not a stable build, but I can put this on there if that is the recommendation.
