Hi, I am not very sure if this error belong to ntfs-3g or linux-usb, but the dmesg says a lot about USB devices so I am reporting it here. Correct me if I am wrong. I upgraded to Linux 3.13.5 and found my USB hard disk does not work properly. But this bug only occurs when mounting an NTFS partition. I have three different USB hard disks, two of them containing NTFS partitions. I tried with both of them, and confirmed that only mounting NTFS partitions will trigger the bug. Mounting ext4 partitions in these three disks does not trigger the bug (and everything's fine). I've attached an annotated version of dmesg below. Please read my comments in that file for more details. -- Sascha Weaver
