Hi all! I have the same problem here : The usb writing performance drops when writing on usb-storage device.
* There is only a problem when writing, reading is ok, writing to a filesystem, to the partition or to the hdd make the problem happen. * I suspect this is not the same issue as the one ubuntu one, because I don't have usb reset device messages. * I have tested the same kernel version on a x86 machine and is unaffected, but it has another usb controller. I can't test a x86 kernel on my amd64 machine, because it is used in production...
