Thanks for the feedback.

The current kernel might just be loading a newer firmware that has a regression. It may very well be a regression in iwlwifi (kernel or firmware). What you can try is to use an older firmware. kernel 4.0 can still load -9.ucode and up. So you can just try to downgrade the firmware. Please use: ethtool -i wlan0 to check the version of the firmware. Don't rely on the information in modinfo.
