spin_unlock_irqrestore. I suggest you look at floppy.c, swim3 was partially based on it, see how it does it's locking. > With all of the other irq handling functions replaced, except > that one (local_irq)enable), the machine locked up and I had to > do a hard reboot. There is also available somewhere the mklinux floppy driver source, which contains bits from Apple that can be re-used, and has all the infos you may need about the HW Ben. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
