Hi,

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.

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

now connecting to my WPA-802.1X with a Intel 7260 fails, see dmesg.
From the wifi's wpa_supplicant file (actually wicd somehow
accumulated
different ones for this SSID, but the following should be it):
proto=RSN
key_mgmt=WPA-EAP
pairwise=CCMP
eap=PEAP
phase2="auth=MSCHAPv2"
Meanwhile my WPA2-PSK at home still works.
According to the dmesg you attached, it seems that we're bouncing
between two APs:
[ 214.644607] wlp2s0: authenticate with 9c:1c:12:c1:26:82
...
[ 214.798595] wlp2s0: deauthenticated from 9c:1c:12:c1:26:82

[ 218.054498] wlp2s0: deauthenticated from 18:64:72:26:de:22
(Reason: 3=DEAUTH_LEAVING)
It seems that your system is trying to connect to two different APs
forth and back. After each association succeeds, the userspace seems
to trigger a deauth (DEAUTH_LEAVING) and goes to the other AP
again...
This sometimes indicates that two instances of wpa_supplicant are
competing with each other. Can you check whether you have more than
one wpa_supplicant instance running?
In any case, there seems to be a driver bug at some point, because we
get a firmware SYSASSERT. To debug that, could you follow the
directions in our debugging wiki page [1] and create a bug in
bugzilla?
Please provide trace-cmd logs (as explained in the wiki) so we can
try
to figure out what is going on.
One final question, was this working before you upgraded to iwlwifi
-next 5bff6536f742?
Thanks for reporting!
