GTA02 Interrupt storm from SDIO on suspend?

Hi Werner -

Balaji mentioned last night he traced the reason for the slow suspend
action to "WoW" interrupts or at least AR6001 territory, since if he
didn't have it in the kernel he got the ~1s suspend that we have seen
before.

The actual wake WoW interrupt is rising edge, I wonder if this is
actually another manifestation of the 2442 SDIO controller interrupt
spew that we discussed briefly a few weeks ago?

If there is just complete spamming of that interrupt for some reason, do
we disable it on bus suspend for SDIO and enable it on resume?

Any other clues about it?
