I'm experiencing a fairly random system lockup on a am3359 based embedded board with musb and with current 3.12 kernel and git current. (The problem can was reproduced with 3.11 series also). It can be triggered with full duplex usb audio (I use USB headset to record and play, tried two different models). I'm using musb in PIO mode (DMA mode doesn't work better), and have tried both host and otg port. The lockup is happening somewhere between 1 to 60 minutes of full duplex audio, at a random point. Then, the system is totally locked up, no debug uart output, no response to ping etc and has to be powered down. Is there something known wrt musb lockup ? I have reproduced this with 2 different headsets and two boards, am3359 based both. --Mika -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
