https://bugzilla.kernel.org/show_bug.cgi?id=89511 Bug ID: 89511 Summary: USB-storage mount error Product: File System Version: 2.5 Kernel Version: 3.2.63 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: ext4 Assignee: fs_ext4@xxxxxxxxxxxxxxxxxxxx Reporter: itou_jun@xxxxxxxxxxx Regression: No When my USB-storage does mount, it becomes the error. It occurs from ver.3.2.63 and does not occur in ver.3.2.62. I ride below dmesg. It reappears in this series of io data by all means. I confirmed that hardware did not have a problem. The following changed kernel in menu in the same environment and tested it. Because a write is not done to become the read only, please help me. Even ext3 format occurs. I doubt file system. Thank you. === Linux sv-server 3.2.62 #1 SMP Mon Dec 8 16:11:25 JST 2014 x86_64 GNU/Linux === [ 35.262592] usb 1-1: new high-speed USB device number 2 using ehci_hcd [ 35.799983] usb 1-1: New USB device found, idVendor=04bb, idProduct=0109 [ 35.799986] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 35.799988] usb 1-1: Product: I-O DATA HDZ-UES [ 35.799990] usb 1-1: Manufacturer: I-O DATA DEVICE INC.
