hi everybody,
as an experiment on this item I compiled a kernel with modified
config: I removed acpi completely and additionally deactivated the
option "enable tickless..." (or so..). Then I booted the kernel with
standard options. Result: Ardour behaves as it should, everything
works just fine, system audio performance at it's best! Obviously
there is a diffenrence between booting an acpi-enabled kernel with
option "acpi=off" and a kernel built without acpi capabilities. Maybe
somebody has an explanation - I don't... thanks for attention anyway

Interesting!
So my guess with cpufreq and clocksource was wrong.
It's dyntics vs. acpi=off
What if you disable dyntics, and boot with acpi enabled?
