Using TSC really dropped us down. I don't know wh\y the timekeeper
says tsc is unstable. We ran our system for an 8 minute cycle and
timed it with a stopwatch, and it was accurate to the second.
On our test irq0 usage dropped from 19% to 13%. Thanks for the help,
guys.

I forgot to mention. In order to keep tsc as the clockdev I disabled
the code in the kernel that removes it as the clocksource.

Even when idle=poll or nohlt the kernel disables the tsc as clocksource ?
Also note that Xenomai does not care if Linux uses the tsc as
clockso
