According to SysRq-P, my system gets in an infinite loop on bootup with notifier_call_chain calling irda_device_event repeatedly. This is triggered by toshoboe_open calling register_netdevice. This is with everything irda-related built-in (I don't like modules); it was working in 2.4.1-ac8. Is it possible that the irda_device_event notifier is added twice somewhere? It appears to me this would result in the observed loop, as if the irda (priority=0) is on the end of the list and the same notifier is added, it will position itself at the end of the list again and set it's own 'next' to a pointer to itself (twice), if I read it correctly.
