[PATCH] ppc32: Fix IDE related crash on wakeup
I noticed an occasional crash on wakeup from sleep on my powerbook (strangly never happened before, probably timing related) that appears to be due to a dangling interrupt while the chip is put to sleep and beeing reset on wakeup. This patch fixes is by disabling the irq in the ide pmac driver while asleep and only re-enable it after the chip has been fully reset. This is safe to do so as the interrupt of these apple IDE cells is never shared.
