We are not sure for now.

Yes wifi scan.

Yes lecroy trace, yes we do see Assert_INTx and Deassert_INTx happening when we do interface link up.
When we have less debug prints in Atheros driver, and do wifi scan we see Assert_INTx but never Deassert_INTx,

The interrupt behavior is changing w.r.t amount of debug prints we add. (I kept many prints to aid debug)

But if we have less debug prints it does not reach EP handler sometimes, due to following
Condition in "kernel/irq/chip.c" in function handle_simple_irq
if (unlikely(!desc->action || irqd_irq_disabled(&desc->irq_data))) {
desc->istate |= IRQS_PENDING;
goto out_unlock;
}
Here irqd_irq_disabled is being set to 1.
With lesser debug prints it stops after following prints:
