Hi,

 > seems that your system is trying to connect to two different APs 
forth and back

Yes, this is a major network with multiple APs for each of its SSIDs 
always available. Unlike my single AP home network, unsurprisingly.

 > whether you have more than wpa_supplicant instance running

I disabled wicd, invoked wpa_supplicant manually and checked with pidof, 
there isn't. I also checked for changes with wpa_supplicant 2.3 vs git, 
none.

 > was this working before you upgraded to iwlwifi-next 5bff6536f742

That's the weird part, IIRC it and the 16er firmware actually were 
working fine *with* it (I had 4.2-RCs running with available 
iwlwifi-next commits for weeks), which is why I was inclined to blame 
net.git until I found out that it currently doesn't work with the 
vanilla Arch 4.2-3 kernel either. Honestly no idea why.

But I'll check with iwlwifi-next-for-kalle-2015-08-23 tomorrow.

 > directions in our debugging wiki page

Two remarks on that page:
iwlfwdump.sh should probably get a note about chmod +x
trace-cmd is not part of standard kernel packages and thus should get a 
note that it may need to be installed separately

Since I wasn't aware of the latter, I'll only be able to post a trace in 
a bugzilla report tomorrow–

– if that isn't bugged as well: "echo 1 > 
/sys/kernel/debug/iwlwifi/0000\:02\:00.0/iwlmvm/fw_dbg_collect" 
currently yields a "file exists", cat'ing it an invalid argument error, 
"echo 1 >>" ostensibly works but shows in dmesg as (1), see "excerpts" 
attachment.

(2) shows an example of what wpa_supplicant currently prints. This 
continues ad inf, and at some non-predictable point the driver bug(s?) 
and/or FW reset appear in dmesg. (3) shows two more variants I got with 
net.git (now at 7845989) and Arch's 4.2-3 kernel.

dmesg is also spammed with "r8169 0000:03:00.1 enp3s0f1: 
rtl_counters_cond == 1 (loop: 1000, delay: 10).", but that's prob an 
unrelated bug which has been there (but far) less frequent since early 4.2.

As for net.git kernel config, "grep IWLWIFI":
CONFIG_IWLWIFI=m
CONFIG_IWLWIFI_LEDS=y
CONFIG_IWLWIFI_OPMODE_MODULAR=y
CONFIG_IWLWIFI_BCAST_FILTERING=y
CONFIG_IWLWIFI_UAPSD=y
CONFIG_IWLWIFI_DEBUG=y
CONFIG_IWLWIFI_DEBUGFS=y
# CONFIG_IWLWIFI_DEBUG_EXPERIMENTAL_UCODE is not set
CONFIG_IWLWIFI_DEVICE_TRACING=y
