This line from earlier in the kernel log is highly suspicious: > [ 46.330470] usb-storage: Error in queuecommand_lck: us->srb = > ffff88080c532600 This means that the SCSI midlayer called the queuecommand routine twice with no intervening completion, even though the maximum queue depth is only 1. Mikhail, is this bug reproducible? If it is, can you post a usbmon trace showing the events leading up to the bug? Does the bug occur if the device is plugged into a USB-2 bus rather than a USB-3 bus? Alan Stern This occurred when I did first reboot after kernel update from 3.14.5 to 3.14.6. After second reboot I have not seen this issue. And I did not plug/unplug any USB devices when it occurred. When I reconnect my USB3.0 10 port hub only occurs this:
