on initial driver setup I get: [ 1.564855] iwlwifi 0000:03:00.0: firmware: direct-loading firmware iwlwifi-7260-9.ucode [ 1.565049] iwlwifi 0000:03:00.0: loaded firmware version 23.214.9.0 op_mode iwlmvm ...

Sine I have updated to latest https://packages.debian.org/jessie-backports/firmware-iwlwifi package from backports the error hasn't occured anymore. You could also try to update to this package from backports. You can also check if this package has the latest drivers included for your wifi card. Here https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi is a list which .ucode is needed for which wifi card on each kernel. Are you running 4.1 kernel from jessie backports https://packages.debian.org/de/jessie-backports/linux-image-amd64? Because what is written in the list on kernel.org, if v13 is expected, it is for kernel version 4.1+. In jessie-backports latest wifi driver for you card is v10, as seen in your log, which is loaded as the most recent one. This could be the reason why you are getting this error. So you could try to download https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-7265-ucode-25.30.13.0.tgz and copy the two .ucode files to "/lib/firmware" were also the other iwlwifi-****-*.ucode files are located and then try reboot and check dmesg if error still exists (because this will bring you latest intel driver for your kernel). Or you go back to Jessie's normal kernel 3.16 and use the wifi driver package from jessie-backports. So two options, going back to old kernel and package from backports or manually "install" driver for your actual kernel. This is just what I could figure out, I am not an expert, so no warranty! :) Please let us know if this helped you. > Joni Orponen <joni.orpo...@gmail.com> hat am 9.
