Bug#862605: Missing ondemand CPU governor.

[dE <de.techno@gmail.com>]

Package: linux-image-3.16.0-4-amd64
Version: 3.16.39-1+deb8u2
Severity: serious

A kernel update removed the cpufreq_ondemand.ko kernel module. Don't 
know exactly which version. The module was build as per the kernel 
configuration --

grep -i ondemand config-3.16.0-4-amd64
CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=y

And is the default (and missing).

The kernel now defaults to powersave.

So it appears that all servers and desktops are now running in 
'powersave' mode now after an update.

Requesting check of other missing kernel modules if this is indeed a bug.
