Hi, i was testing acpi in my computer. i found problem with suspending usb device.
i test: echo 1 > /proc/acpi/sleep and i get this output from kernel.log: Oct 24 16:02:33 prog3 kernel: PM: Preparing system for suspend Oct 24 16:02:33 prog3 kernel: Stopping tasks: =====================================================================================| Oct 24 16:02:33 prog3 kernel: uhci_hcd 0000:00:07.3: Unlink after no-IRQ?
