  SVN rev 182527 on 2008-08-31 10:17:40Z by ed
  
  Disable processing of output data after disabling scroll lock by force.
  
  The syscons code disabled scroll lock inside sc_cnputs() if it's going
  to print a system message. The code currently wants to process any TTY
  output data as well, but we cannot do this, because the TTY lock is a
  sleep mutex, while cnputs() picks up a spin mutex.
  
  Disable the code for now. It solves a panic when a console message is
  printed while scroll lock is enabled. One solution would be to
  initialize a task structure here.
