I confirmed this *again* in a much easier way, by using the RF-toggle switch to cycle the wifi manually on the laptop.
On 4.6, this makes the firmware crash (same error as above). With the upgraded iwlwifi module and upgraded firmware, the error goes away. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1577957 Title: Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation) Status in linux package in Ubuntu: Confirmed Bug description: The stock firmware for this device /lib/firmware/iwlwifi- 7265D-16.ucode is crashing. Downloading the latest firmware (/lib/firmware/iwlwifi-7265D-21.ucode) isn't supported by the existing iwlwifi driver, and so the driver likely needs to be upgraded (or downgraded as well (https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/backport- iwlwifi.git/?h=release/LinuxCore18). I can also confirm that wifi *did* work successfully on 15.10 before upgrading to 16.04, although the kernel module required frequent restarts due to this bug: https://bugs.launchpad.net/ubuntu/xenial/+source/linux/+bug/1570595 A detailed message about the firmware crash is located in the attachment from dmesg output.
