    Hi,

    I have an external 120 GB USB-IDE-Disk connected to my USB 2.0 host
    controller.
    Used Linux version ist Mandrake 10 (kernel 2.6.3) on x86 Athlon and
    Epox onboard USB.
    The drive is detected, I partitioned it and formatted the partitions.
    While copying small files, the drive is quite fast (~ 10 MB/s). If I
    copy more than 100 MB on the disk, the whole system hangs until I
    unload ehci-hcd.

    The same configuration works under win2k without problems...
    It also works with USB 1.1 (OHCI).
    Kernel 2.4.22 (Mandrake 9) resulted in the same problem as soon as the
    EHCI-driver has been used.

    Does anyone know what the problem is and how it can be solved?

    Thanks,
      Jochen
