It didn't apply to -rc7, but I managed to apply it manually
(apparently you made this for wireless-testing?) and added the #if 0.
After 7 hours uptime with the driver, no apparent interrupt storm.

I'll do more thorough testing later, but I have a 3 hour drive today,
and some packing to do, so it'll need to wait a bit.

Yeah I did it for wireless-testing. Good to hear this so far has
solved the issue. I'll port it to 27 and post it once I get your
blessings that this fixed it by a Tested-by.
