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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
