Comment 39 for bug 126140

The powersaving trick works, my EeePc (4G) doesn't hang on poweroff anymore. And I didn't notice any odd behavior playing sounds, nor any lag. Assuming this will also save some battery life I will start using it.

I followed the instructions supplied at the thinkwiki link. To write to sysfs you need to logon as root, using sudo won't work. So create a password for root, or better yet, include those commands in an init script.

Thanks Sitsofe!
