No.
I tried to move the SC_OP_INVALID check until after the call to
ath9k_hw_getisr in ath_isr. But that caused the kernel to freeze
IIRC.
What I also tried and failed to do a hardware reset before
request_irq gets called. For ath9k_hw_reset I need an initialized
ath_hw struct, but that's done after request_irq in
ath9k_init_device. I remember I tried to delay request_irq, but for
some reason that did not work out either.

If you have an idea how to do this, I think that would be most
helpful.
