Panic indication would seem a valid excuse for having something in the kernel, yes. But that could also be just a "panic-only" driver. It may have to violate quite a few rules anyway, to be able to get through to the LED controller when the system is in trouble. We don't have any easily GPIO-accessible LED, do we ? - Werner _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
