I can confirm that BIOS 1.26 fixes this. Funny, 2nd level support swore
up and down that there wasn't a problem...

I am in contact with Acer Level 2 support and they have been friendly
but unable to help me out. According to them, the D250 with Windows 7
they have for testing shows no issues like this at all. It fully runs at
1.66 GHz.
I was asked to return my laptop to second level support for a closer

You are absolutely correct that this is a real bug, but you overestimate
the area of function for this particular bug tracker. This is a BIOS

Lenovo has no public issue tracker so you never can tell.
I'm discussing the problem with their local support contact. H

Most likely the reason is different power profiles (by default XP has
EIST off).

Interesting news: MSI issues a BIOS update for its Atom N280-based
netbook Wind U100 Plus with a changelog:
Modify the string of CPU Frequency for W7

As can be seen in the discussion above this
I just noticed that Acer released a new BIOS for AOD250, with no release
notes as usual.
Has anybody tried? Does it fix anything?

Your SSDT table is exactly the same as mine, except for th
I tested the BIOS from Acer and got 1.66GHz but no power saving, as I
expected after comments here. I replied with a compliment, asking for
another attempt with focus on _both_ performance _and_ power saving. I
also asked why we can't just get a BIOS with tables saying we have four
speed steps.

I agree this shouldn't be a Ubuntu bug, but more people will probably
look for this issue, so I suggest we keep it open until we see how it
plays out with Acer. :)

I can confirm that the kernel is getting the wrong CPU speed from the

but no frequency scaling (off course, since acpi is disabled).
Does anyone know of a working coreboot image for Aspire One? ;)
