Greetings,
(resending plaintext - oops)
I'm seeing failures to authenticate with a WPA2 secured AP using ath9k
based cards on wireless-next:

I've tried loading ath9k with nohwcrypt=1 and see the same.
I do not have any trouble with an ath10k card in the same system:

Here's the PCI info for the two cards:

88E8057 PCI-E Gigabit Ethernet Controller [11ab:4380]
09:00.0 Network controller [0280]: Qualcomm Atheros AR9580 Wireless
Network Adapter [168c:0033] (rev 01)
I don't know when ath9k last worked honestly. I usually use them under
OpenWrt which has its own patches against periodic updates of linux
backports. I noticed this first with Ubuntu 16.04 with the Ubuntu 4.4
kernel, saw it still with the Ubuntu 4.8 kernel, then repeated the
issue in wireless-next.
Any ideas?
Regards,
Tim

an easy check for that is:
# root@box:~ DEV=wlan0; basename $(readlink /sys/class/net/$DEV/device/driver)
iwlwifi
# output is e.g. ath10k_pci or ath9k

It's ath9k for sure... several different ath9k radios fail the same
way: WLE350NX, WLE200NX, WPEA-127NE, SR710E. I'm surprised as heck as
well. I only put the ath10k radio in to ensure I don't have some
configuration issue (and have since removed it and only test with 1
card at a time). I've also ensured that a variety of radios/drivers
work with the same Ubuntu xenial (16.04) userspace and kernels such as
ath10k, carl9170, iwlwifi.
Is there some userspace configuration issue I may have related to
regdomain on ath9k that perhaps isn't applicable on other drivers?
Note that depending on the kernel version I don't always get the same failure.
Here is Ubuntu 4.8.0-30-generic which is where I originally saw the
issue and started troubleshooting. In this case we auth/assoc and then
immediately get disconnected from the AP:

This turns out to be caused by interrupts not getting caught. The
target board used here is an IMX6 and its driver and/or PCIe host
controller apparently doesn't support both MSI and legacy interrupts
at the same time thus this breakage occured when the kernel started
enabling MSI by default for IMX6
(3ee803641e76bea76ec730c80dcc64739a9919ff).
Can ath9k can be enhanced to use MSI?
How many other cards/drivers out there don't support MSI?

Interesting. Are you sure wlan0 is ath9k and wlan1 is ath10k?
ath9k is quite stable - I have AR9462 and works fine with 4.4 and current.
So, I would suspect some issues with ath10k :)
What if you will modprobe -r ath10k_pci and next run the test?
