So, I tried setting clocksource=tsc, and the system hung on boot.
I reviewed the BIOS settings and found that ACPI was disabled, probably
because I thought it was needed because of the acpi=off kernel args.
So, I re-enabled ACPI in BIOS.  That didn't fix the boot issues, but it
does seem to have enabled ntp to run.  Now I'm getting errors about writing
the drift file from SELinux, but that's a seperate issue.  So, I think
I'm back in business.

/usr/sbin/ntpq -p -n

Thanks for the clues, Chris
