The PSUbuntu developers are working hard on making Hardy Heron work on the PS3, but being a community maintained Ubuntu-port they need your help finding and fixing bugs.

If you’ve managed to upgrade to 8.04, you’ve recompiled your kernel for the PS3, and you know how Ubuntu packaging works then you can probably help out by posting any bugs and issues you encounter to the ubuntu-ps3-port launchpad page.

If you are a developer and want to take part in psubuntu development; the ubuntu cell mailing list is the place to be. To get updated on current issues, browse through the archives and check Dan Munckton’s Status Update emails.

For instant contact with developers, use the IRC channel #ubuntu-ps3.

You’ll find more information in this forum thread.
