I've upgraded to Linux 3.2 and roaming failed randomly again,

after the failure it may recover
sometimes by switch off and on the wifi button on laptop,
sometimes by "modprobe -r iwlwifi && modprobe iwlwifi",
sometimes by "stop networkmanager and start networkmanager",
sometimes recover automatically 10 or 20 minutes later,
sometimes never recover, infinitely looping (can only move to other
place, but same place has good wifi coverage verified by other
colleagues, win/mac users)


have checked it has your recent 78feb35 & 81670a4 commits,
$ git log -n5 --no-merges --oneline v3.2 -- drivers/net/wireless/iwlwifi/
96f1f05 iwlwifi: update SCD BC table for all SCD queues
78feb35 iwlwifi: allow to switch to HT40 if not associated
81670a4 iwlwifi: tx_sync only on PAN context
123877b iwlwifi: do not set the sequence control bit is not needed
9995ffe iwlwifi: change the default behavior of watchdog timer
