Hi Christopher,

After applying the BIOS update, I've managed to do about 20 GB worth of
transfers (some photos) via the USB 3.0 port without any issue.
Previously, this transfer would have been long enough to trigger the
kernel panic.

I will do some deliberate testing with dd today, and if I can't
reproduce it, I'll consider it fixed and mark this bug Invalid. Thanks
for your suggestion!

Title:
  Kernel panic with USB 3.0 mass storage device

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have the following hardware:
  * Dell XPS 13, which has two USB ports—one USB 2.0, one USB 3.0.
  * Sans Digital MS4UM+B (http://www.sansdigital.com/mobilestor/ms4umplusb.html) with four hard disks.

  I am trying to transfer data between two of the disks in the
  enclosure, using dd.

  When I connect the enclosure to the USB 2.0 port, dmesg contains:
  [  892.056502] usb 3-1: new high-speed USB device number 3 using xhci_hcd
  [  892.073556] usb 3-1: New USB device found, idVendor=152d, idProduct=0551
  [  892.073567] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=5
  [  892.073573] usb 3-1: Product: USB to ATA/ATAPI Bridge
  [  892.073578] usb 3-1: Manufacturer: JMicron
  [  892.073582] usb 3-1: SerialNumber: DCA1861915FF
  …and I can transfer hundreds of gigabytes without issue, at USB 2.0 speeds (20 MB/s). 

  When I connect the enclosure to the USB 3.0 port, dmesg contains:
  [  658.873399] usb 4-2: new SuperSpeed USB device number 2 using xhci_hcd
  [  658.890861] usb 4-2: New USB device found, idVendor=152d, idProduct=0551
  [  658.890872] usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=5
  [  658.890878] usb 4-2: Product: USB to ATA/ATAPI Bridge
  [  658.890883] usb 4-2: Manufacturer: JMicron
  [  658.890887] usb 4-2: SerialNumber: DCA1861915FF
  …and I invariably experience a kernel panic shortly after data transfer begins. I attach two screenshots. If I can manage to probe dd (sudo killall --signal USR1 dd), the transfer appears to be going at USB 3.0 speeds.

  The enclosure was not powered on when I ran 'ubuntu-bug linux' to
  report this, so I'll attach another dmesg showing the device being
  attached to first the USB 3.0, then the USB 2.0 port.
