From the bug report[2] it looks like it is 100% reproducible using a 3.12-rc6 kernel simply by pressing any button on the IR remote. >>From the stack trace, it looks like input_event is invoked with the input_dev parameter set to NULL, which seems to indicate that appleir_input_configured is never invoked. Any ideas? [1] https://launchpadlibrarian.net/154942024/macmini-oops.jpg [2] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1244505 Cheers, -- Luis
