I was totally mistaken.  I thought it was fixed.  It worked for a
brief time last night and then I made the big mistake of rebooting. 
Now once again I keep getting the damn error and Ardour gets tossed
out of the jack network.  Now it happens with both internal and
external USB2 drive.  I'm still reading replies.  I got so frustrated
this damn thing almost died a brutal death...and then that would be a
waste of a lot of money...

What happened last night is that I had acpi turned off and I had
turned on memlock.  That first time it worked great and I was able to
play through an entire session without a single xrun.  But then I
rebooted and now it is once again buggered to hell.
