I have an RaLink wireless card (rt2500) and am also seeing excessive events/0 usage. For me it only happens intermittently. I often see it about 30 seconds after login, but sometimes it's fine. I've not seen anything in any logs which suggests a problem.
-- events/0 uses all of cpu, causes big slowdown https://launchpad.net/bugs/67126 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
