Armada 370 USB reset #77
Description
I'm hitting an issue on various Armada 370 systems, where the orion-ehci USB host gets hard reset during file transfers to certain models of USB3 flash drives. The Linux kernel usb_storage debug messages report that occasionally a bulk transfer will fail. I've seen error code 104 (ECONNRESET) and 71 (EPROTO) reported so far.
I've tried vanilla kernel.org kernels from 4.1 to 4.10-rc6, all with the same issue. However, the old Linux 3.2 LSP kernel survived the same test over multiple days.
I have a SanDisk Ultra Fit 128GB and 32GB USB3 sticks here that can reproduce it easily within a few minutes. Other USB storage devices that I have tried work fine.
