Bug Description
Hi,
Since I updated from Ubuntu 16.04 running kernel 4.8 (-generic-edge or something similar) to 17.04 running 4.10.0-20-generic I get a stack-trace every time I launch hostapd.
This issue did not exist prior to the upgrade and is 100% reproductible.
My WiFi chipset is a Intel Corporation Wireless 7260 (rev bb), and I am using a very simple configuration for hostapd.
The access point does work even after the stack-trace appears but it becomes unstable after a day or two, dropping clients and sometimes freezing the system entirely.
When it doesn't freeze the system I am usually able to get the access point to work again by rmmod'ing iwlwifi and iwlmvm then re-inserting them and restarting hostapd. Every restart produces the same stack-trace.
The bug is similar to https:/
Let me know if you would like me to attach some dmesg logs or any other kind of evidence.
I can also perform additional testing if required.
