Success with Suspend2

It worked, it really worked …

I’m considering buying or building a new PC. Something with Intel Core 2 Duo. While these CPU’s require less power under load than their AMD equivalents, they consume more power in idle situations. It frequently happens, that the PC at home is idling for extended periods. So, I thought, I should give the “Suspend2” patch set for the Linux kernel a try. This is, what I did today with my company PC and as fas as I can tell, I worked flawless.

This are the steps for my Gentoo system.

Include these line in /etc/portage/package.keywords


and emerge the most recent versions of these packages (actually I went for the suspend2-sources-2.6.20-r6 kernel sources instead of 2.6.21). Configure and compile the kernel according to the HOWTO documentation. Additionally I blacklisted intel_agp and agpgart in the file /etc/modprobe.d/blacklist to rely on the Nividia internal NvAGP driver.


blacklist intel_agp
blacklist agpgart

and executed “update-modules force“. In /etc/hibernate/blacklisted-modules the nvidia module was listed. After suggestion from the net I commented it, since my Nvidia driver is recent enough.

After that, I rebooted the new “suspend2” kernel and tried it and I’m happy to report, that it really worked. Now it only need to work on my PC at home and then on the new PC. Anyway here is the lspci output from this configuration:

In the market for a new PC

My current AMD 2800+ system is getting old. With all my multimedia work (en- and decoding MP3s, cleaning video recordings from advertisement) and the Gentoo compilation stuff I could use some more CPU horse power. Originally I thought to purchase some brand name computer, but since I came across the “System Builder Marathon” articles on Tom’s Hardware Guide (Part 1, Part 2, Part 3, Part 4) and remembered the article in c’t 26/06 I changed my mind. I’ll guess I’ll end up with a large Calc/Excel sheet listing all the different options.

Anyway, I’ll probably leave the AMD arena for now and aim in the direction of a Intel Core 2 Duo E6600, Nvidia 7600GS (I don’t do any gaming) and some 500GB hard disc, trying to build the PC as quite as possible. As is happens, there’s just an interesting article on “Tom’s Hardware Guide” as well.


Am Dienstag ist “unser” Schwede wieder abgereist und wir sind zur relativen Normalität zurückgekehrt. Martin war ein sehr angenehmer Zeitgenosse. Steffen und er haben ähnlich gelagerte Interessen. Und die bestanden nicht primär darin, eine Woche “Party” zu machen, wie das bei einigen anderen schwedischen Austauschschülern der Fall war, wie einige Gasteltern erzählten. Martin ist jedenfalls ein gern wiedergesehener Gast.

Das Projekt “GSN goes Europe” ist für uns damit erstmal beendet.

Besuch aus Schweden

Nachdem Steffen ca. Oktober 2006 mit dem Projekt “GSN goes Europe” für eine Wochen in Schweden war, ist jetzt der Sohn der Familie, bei der er zu Gast war für ein Woche hier. Die meiste Zeit sind die Jungs ja mit diversen Unternehmungen der Schule beschäftigt. Am kommenden Samstag dürfen wir als Familie dann das Programm gestalten und für entsprechende Belustigung sorgen.
