I'd appreciate anyone pointing me in the direction of information regarding ACPI support.

I've been running Ubuntu since Dapper and with the upgrade of the box I'm typing on right now I'm running 8.04. ACPI support was not that good in Dapper and has grow progressively worse with each release. Shutdown won't even work properly on this box now and this box has a 2006 BIOS. Similar results on my other boxes. I do have a somewhat technical background so I might be interesting in working on ACPI support given the right place to start learning.

Certainly there is no need to fill lanuchpad will additional reports and it is not surprising to see 2 of the top 3 posts in Brainstorm are related to ACPI support. We all know it is broken for many many people, what can be done to correct the situation?

Any info appreciated.
