Public bug reported:

Following up on Bug #962712 which was marked as invalid, instead of
fixed (gee, thanks...) I'm using Ubuntu 13.10 and this still happening
pretty badly.

Steps to reproduce:

1) Unplug laptop, plug-in second monitor, drain battery until OS warns user and asks her to plugin laptop
2) Plugin laptop

Expected: Laptop works normally
Actual: Laptop slows down severely.

Drilling down, run `cpufreq-info`

Expected:
driver: acpi-cpufreq [...]
current policy: frequency should be within 800 MHz and 2.80 GHz.

Actual: 
driver: acpi-cpufreq [...]
current policy: frequency should be within 800 MHz and 800 MHz

-=-=-

Drilling down, this is known, lingering problem, and is not "invalid",
please triage instead of sweeping under the rug
