    SubjectUSB storage crash report in 2.6 SMP
    Date
    Copying a large amount of datas (several gigabytes) between two USB 2.0 attached
    disks will crash any Linux 2.6 SMP kernel, including 2.6.9-rc3.

    The stack report is:
    qh_completions 0x7B/0x118 [ehci_hcd]
    scan_async
    ehci_work
    echi_irq
    handle_IRQ_event
    commnon_interrupt
    default_idle
    default_idle
    cpu_idle

    The crash will append on any attempt to copy something like 100 GB.
    Copying something like 1 GB or less works nicely.
    Switching to an UP kernel solves the problem.
    Switching to a 2.4 kernel solves the problem.
    I tested it on two different machines, with two different disks sets.
