You can try freezing the output by pressing the scroll-lock key
or Ctrl-S. Unfreeze the output, respectively, by pressing scroll-lock
again or Ctrl-Q.
Different things will happen depending on what facility is displaying
the output. If you're viewing kernel output directly, and you block
additional output by freezing the screen, you may get a non-recoverable
kernel oops[1]. The chance of a kernel oops increases the longer you
keep the screen frozen. If you get an oops, hard reboot the machine by
holding down the power button for 5-15 seconds. If you're viewing
multiplied syslog[2] output, freezing the screen won't prevent
additional errors from occurring, and the machine may reboot before you
see all the output.
