So the best I got was the attached screenshot of an oops. It is clearly the iwlwifi driver crashing here and killing the machine, but I have no idea why.

Incidentally, if this really is the same bug I have, you might want to
remove the iwlagn module completely, even loading it once is a bad
thing, it has started to corrupt things here entirely by making DMA go
to random locations.

with the release of -rc7 i was starting to wonder what had happened to this bug,
i'm not affected by it(other hardware) but from what i gather it's a serious problem?

i have always wondered what people affected by this find if they revert the
"memory allocation optimization" patch

apologies if this is a too random stab in the dark, just sounds like we might want to fix this
before .27. And since there seems to be no git bisects that pinpoint the problem ..
i figured i might as well send this.
