--- Comment #1 from Timo Juhani Lindfors <timo.lindfors at iki dot fi> ---
The issue occurs also with systemtap 2.2.1 so it is not a systemtap regression.
Downgrading kernel from 3.10-1-amd64 to 3.8-2-amd64 seems to let me use
systemtap again.
Looking at "git log v3.8..v3.10 -- drivers/cpufreq/cpufreq.c" my guess is that
this is caused by

cpufreq: handle cpufreq being disabled for all exported function.
When disable_cpufreq() is called some exported functions are still
being used that do not have a check for cpufreq being disabled.
Add a disabled check into cpufreq_cpu_get() to return NULL if
cpufreq is disabled this covers most of the exported functions. For
the exported functions that do not call cpufreq_cpu_get() add an
explicit check.
