[Kernel-packages] [Bug 1577957] [NEW] Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation)
Public bug reported: 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.

Sure, it takes about a day for my laptop to hit the error. Will respond as soon as possible. Heads up: The bug does appear to have been fixed in the latest version of the iwlwifi module from master and latest firmware - I upgraded the 4.4 kernel to the latest version of the modules and signed them and latest firmware (-21) and my wifi hasn't crashed yet. -- 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: Incomplete Bug description: The stock firmware for this device /lib/firmware/iwlwifi- 7265D-16.ucode is crashing.

[Kernel-packages] [Bug 1577957] Re: Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation)
Alright, a BIOS upgrade didn't help. Still crashes. More or less it consistently fails after a day or two, but I have noticed that if I use the wifi continuously for a long work-day, and never allow it to sleep or never switch to ethernet, the wifi stays running. So, the crashes do seem tied to powercycling the radio - either via sleeping a few times throughout the day or by powering off the radio and switching to ethernet. It can sometimes take multiple days of powercycling the radio before it crashes on the other hand, if I have a lot of meetings one day and I cycle it frequently, then it crashes within in a few hours. If I avoid powercycling, the wifi (generally) seems to stay on. This seems to indicate that there's some "buildup" of state in the firmware that only happens after enough cycles to cause the firmware to either not be keeping track of the actual state of the device or some kind of memory corruption that only happens after enough cycling within the firmware. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- 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.
