Was there anything else before the first bug in dmesg? I would predict there to have been some additional debugging info, and probably a USB device disconnect or similar. If I'm correct, there was an io error while writing to the external device, which as of 2.6.37 isn't handled terribly well (and errors in general; in that sense, it's known). -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
