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.
