Title:
  Reading from /sys/devices/system/cpaccess/cpaccess0/cp_rw crashes the
  Nexus 4

Status in Canonical System Image:
  Confirmed
Status in linux-mako package in Ubuntu:
  Confirmed

Bug description:
  I noticed that my Nexus 4 crashed while doing a

  grep "1" -r /

  in an adb shell as user phablet. After narrowing it down, it looks
  like I can reliably crash my device by just doing a

  cat /sys/devices/system/cpaccess/cpaccess0/cp_rw

  as a normal user. After doing it about three times, all aspects of the
  device still work as expected, but it no longer identifies itself via
  USB, not even when in recovery mode. This might be a different issue,
  but it has never happened before, so I do think it might have been
  caused by the crashes.
