Don't disable all interrupts, just disable the relevant one. Also move a couple of printk calls outside of local_irq_save/restore. Tested on a Quadra 660av. Signed-off-by: Finn Thain <fthain@xxxxxxxxxxxxxxxxxxx>
Using disable_irq() is very expensive, and when done from an interrupt handler can deadlock especially on SMP (which I understand might not be relevant here). I really can't see why you'd do things this way, especially since interrupt handlers under Linux now unconditionally always run with cpu interrupts disabled. -- To unsubscribe from this list: send the line "unsubscribe linux-m68k" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
