This kernel boots fine and has no WiFi problems.

You assume a breakage in a different area than wireless or network in general?

Any wild guess?

Not really, but maybe you can pull the other trees on top again and see
if those broke it? I don't really think/hope so but it's possible that
one of my pending pull requests broke it, I guess?

Hmm, I pulled in latest for-john of mac80211(-next) and
iwlwifi-(fixes|next) which did not help.

I am testing next-20130805 and next-20130802 to identify which
Linux-next release is BROKEN.

GOOD: next-20130801 and next-20130802

BROKEN: next-20130805 and next-20130806

Comparing diffs between next-20130802 and next-20130805.

The diff was not very helpful.

$ cd linux-next-20130805

$ git log --oneline v3.11-rc4.. | grep "Merge remote-tracking" | egrep
'net-next|slave-dma|wireless'
7f84622 Merge remote-tracking branch 'net-next/master' <--- BAD
(before slave-dma/next)
3580d24 Merge remote-tracking branch 'slave-dma/next' <--- GOOD (after
net-next/master)
88825c7 Merge remote-tracking branch 'wireless/master' <--- GOOD

So, the culprit commit seems to be in the merge of 'net-next/master'.

( BTW, disabling IPv6 in NM/wifi-setup did not change behaviour -
still disconnected to AP. )
