I can confirm this bug, nothing with rt2500 works after i upgrade from herd 5. Vanilla herd 5 works very good. This is a showstopper for a lot of people in ubuntuforums (feisty fawn)
-- kernel 2.6.12-10-386 breaks rt2500 https://launchpad.net/bugs/39818 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
