Comment 8 for bug 1393085

OK, I just noticed I only have 2 CPU scaling governors now, so looking around I bumped into this:

http://askubuntu.com/questions/544266/why-are-missing-the-frequency-options-on-cpufreq-utils-indicator

I switched to "performance" (it was in "powersave") and now all seems to be working fine. It seems like it was just a problem with CPU scaling.

Nevertheless, this is a very nasty regression, and very hard to find out, as the only evident effect I've seen from it is this slowdown when watching video using the flash plugin (probably because the flash plugin sucks so much, because I could see videos, even in HD, with any other decent video player like mplayer or vlc).

So it seems like the intel_pscale cpufreq driver is kind of broken, the CPU frequency is in fact scaled (I have a small indicator for that and I see it increasing even with the "powersave" governor), but it doesn't seem to calculate correctly the CPU power needed.

Maybe as a workaround the "performance" governor should be used by default. Or maybe I should switch back to the old ACPI driver, as I'm also noticing that the CPU frequency is kept quite high, even when idling, so I'm afraid of the consequences of this in my battery life :-/
