>Description:
when connecting a SATA disk in USB 2.0 enclosure, mounting it and running...

  while ( true ); do tar xzf a_linux_kernel_tree.tgz; rm -rf linux*; done

...in 3 terminals, each with different workdir (within the umass mount), 
eventually messages like this are generated:

  umass0: Invalid CSW: tag 1631723562 should be 2236794

The processes effectively stop writing/reading; 'tar' processes are in state 
'uninterruptible wait' as per ps(1) ('D'). Unmounting the device works, but 
results in messages:

  umass0: BBB reset failed, IOERROR
  umass0: BBB bulk-in clear stall failed, IOERROR
  umass0: BBB bulk-out clear stall failed, IOERROR

Initially, I/O to other disks was still ok, but the morning after, I found the 
box unresponsive when trying to access any disk, and console filled with the 
above messages. 

The device, when attached:
