  Bug in i4btel driver read routine corrected. The conditions in the
  while() clause caused the receive queue to be referenced before checking
  if a channel is connected, leading to kernel panic (do a 'dd
  if=/dev/i4btel0 of=/dev/null' on an unconnected tel device, panic will
  follow). Correction was to reorder the while clause conditions to check
  for connectedness first.
