    Subjectusb-storage, error reading the last 8 sectors, regression in 2.6.25-rc7
    Hi!

    If I boot Asus Eee PC with 8 Gb Transcend SDHC card inserted into the
    internal card reader, 2.6.25-rc7 prints the following:

    [ 9.914968] scsi 2:0:0:0: Direct-Access USB2.0 CardReader SD0 0100 PQ: 0 ANSI: 0
    [ 10.248951] sd 2:0:0:0: [sdb] 15660032 512-byte hardware sectors (8018 MB)
    [ 10.249695] sd 2:0:0:0: [sdb] Write Protect is off

    [ 10.380590] sd 2:0:0:0: [sdb] ASC=0x11 ASCQ=0x0
    [ 10.380590] end_request: I/O error, dev sdb, sector 15660024

    As a result, no sdb device is created by udev.

    If the card is inserted after the boot, it sometimes works fine (I've
    tested with "dd if=/dev/sdb of=/dev/null bs=512 skip=15660000"), and
    sometimes fails in the same way (the same I/O error message, dd
    hangs).

    2.6.24.4 is fine (no problems at boot, always can dd read the whole
    card, all 15660032 sectors of it).

    The other SD card I've got, 2 Gb, also works ok even with 2.6.25-rc7.
