[LAU] Sudden Jack problems

[Peter Desjardins]

Hi.  I'm posting this to complete the story for the archives.

My problem went away after I restarted.  I guess that would have been
a reasonable thing to try first.

The updates I installed via the Ubuntu update manager required a
restart.  Maybe I failed to select real-time mode at the boot menu.  I
should learn how to make real-time mode the default in that menu.

Sorry for the noise.  Thanks for your help.
