Subject: Connecting to a PC while recording causes a crash and loss of the recording.

Connecting to a PC while recording causes a crash and loss of the recording.

Salutation: this Rockbox is some pretty awesome software!

Hardware: Sansa Clip Zip, AMSv2 variant 1
Software: boot 4.0; 515a3c5-140924, and others


Start a recording. While this runs, connect a USB cable and connect to a
PC. The connection will cause a PANIC message:

  ): OOM
pc:30065CA0 sp:3
     A: 30063E2C
     A: 300643E4
     A: 3004DA18
bt end

The file that was being recorded will not exist after the panic (a
chkdsk or similar may be able to recover a fragment).

Encountering this is likely if you routinely use the recording feature
in a busy environment, since when the display is timed out the device
appears off (assuming you don't have headphones connected to monitor the
recording). If you're not mindful, you may forget about the last
recording you'd started, and plug the unit into your PC before properly
ending the recording (I lost an important lecture this way, doh!).

Perhaps a routine needs to be added which checks for an active recording
and ends it before initializing the USB link, or perhaps brings up the
display and leaves the link down for that connection, similar to the way
USB behaves when you've entered [System->Debug (Keep Out)->Battery]
before connecting (i.e. the link with the PC stays off, but the unit
goes about charging).
