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.

You'll be able to find the firmware here: https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/plain/iwlwifi-7260-12.ucode Note that users reported an improvement with -13.ucode, but you'll need 4.1 to use that firmware. The issue you are facing can be caused by a lot of factor and hence it is hard to know if the newer versions will fix your problem, but it is worth trying. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
iwlwifi: Microcode SW error detected. Restarting 0x2000000.
At a Gentoo (hardened) I experienced - starting with hardened kernel 4.0.6-r1 - the (attached) hickup of the "03:00.0 Network controller: Intel Corporation Wireless 7260 (rev 83)" at a ThinkPad T440s. The network stucks till I do restart the network device using /etc/init.d/net.wlp3s0.
