** Description changed:

  [Impact]
  
- Hangs and lockups are observed when lots of USB interrupts occur.
+ Hangs and lockups are observed when lots of USB interrupts occur. The
+ FIQ handling in the dwc_otg driver seems to be particular susceptible to
+ this setting.
  
  [Test Case]
  
  Connect a USB/serial adapter to the Pi. Run 'minicom -D /dev/ttyUSB0'.
  Send data over that serial connection from a remote device. The Pi will
  hang within seconds.
  
  [Regression Potential]
+ 
+ This change enables full preemption which could uncover all sorts of
+ problems like hangs and/or lockups.
