Hi, When I do spin_lock_irq it disables IRQ's which were enabled. What is the reason for disabling all the irq's rather than disabling the specific IRQ line which shares the resource? Wouldn't this be more efficient and would not lose any interrupts especially if I have a critical sensor ADC? Thanks, Gautam. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
