[ Full thread see [1] ]

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. )
