Problem Details: commit b74713d04effbacd3d126ce94cec18742187b6ce "ath9k: Handle fatal interrupts properly" introduced a race condition, where IRQs are being left enabled, however the irq handler returns IRQ_HANDLED while the reset is still queued without addressing the IRQ cause. This leads to an IRQ storm that prevent...
