Bug#849330: firmware-iwlwifi: intel 8260 does not work when using modfile /lib/firmware/iwlwifi-8000C-22.ucode and kernel 4.8
I just upgraded to the backported package... the same file was installed (iwlwifi-8000C-22.ucode), and after rebooting I do not have any problems anymore.

Control: tag -1 moreinfo This firmware file was updated in version 20170823-1, but there was no explanation of what changed. Did it fix the problem for you? Ben. -- Ben Hutchings Power corrupts.

the bug appears at:

so in fact it does NOT appear to be "guaranteed to be aligned". the
assumption may be wrong

Bug#849330:
can confirm this bug. removing 8000-C ucode 22 firmware stub works. before removing, you will get errors 99% of the time upon driver load similar to below: "pcie/rx.c iwl_pcie_alloc_ict" "iwlwifi: probe of" "failed with error -22" in rx.c in function iwl_pcie_alloc_ict around line ~1700 (1747?) could be a memory alignment issue with zalloc upon loading the newer (broken) firmware for the 8260 (rev3a)? just some thoughts again, to reiterate the temporary workaround, just: $ sudo rm /lib/firmware/iwlwifi-8000C-22.ucode and then ensure this gets fixed upstream in iwlwifi-8000C-22.ucode before installing any firmware-iwlwifi updates or hold the package: $ sudo apt-mark hold firmware-iwlwifi remove the hold if / when it gets fixed in debian later: $ sudo apt-mark unhold firmware-iwlwifi

Greetings, I also experienced this bug (Lenovo P50, worked with 4.2.0-1 kernel, fails with 4.8.0-2 kernel). I was able to get things working again by downgrading - but I had to go pretty far. firmware-iwlwifi 20161130-2 did not work firmware-iwlwifi 20160824-1 did not work Downgrading to firmware-iwlwifi 20160110-1, however, worked for me. In case others following this bug are curious: wget http://snapshot.debian.org/archive/debian/20160224T164321Z/pool/non-free/f/firmware-nonfree/firmware-iwlwifi_20160110-1%7Ebpo8%2B1_all.deb sudo dpkg -i firmware-iwlwifi_20160110-1\~bpo8+1_all.deb sudo apt-mark hold firmware-iwlwifi then reboot (or maybe rmmod iwlwifi + modprobe iwlwifi?)

Bug#849330: firmware-iwlwifi: intel 8260 does not work when using modfile /lib/firmware/iwlwifi-8000C-22.ucode and kernel 4.8
Package: firmware-iwlwifi Version: 20161130-2 Severity: important Hello Maintainer, Using a laptop with an intel 8260 wifi chip (HP Zbook 15 G3) and linux kernel 4.8, wifi does not work. This is a known problem; see https://bugs.archlinux.org/task/51271 It looks like the answer is that the debian package does not contain the latest fixes. I can fix the problem by following the directions in the website link given above: - copy / move /lib/firmware/iwlwifi-8000C-22.ucode, and the kernel will then use /lib/firmware/iwlwifi-8000C-21.ucode, which works. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.7.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) firmware-iwlwifi depends on no packages. firmware-iwlwifi recommends no packages.
