mich...@hinespot.com, would the firmware found via https://www- ssl.intel.com/content/www/us/en/support/network-and-i-o/wireless- networking/05511.html provide better results than iwlwifi- 7265D-21.ucode?

[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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577957 Title: Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

mich...@hinespot.com, as per the release notes from http://support.lenovo.com/us/en/products/Laptops-and-netbooks/ThinkPad-X -Series-laptops/ThinkPad-X1-Carbon-20BS- 20BT?tabName=Downloads=Mast:SubNav:Support:Drivers%20and%20Software|Drivers%20and%20Software=false an update to your computer's buggy, insecure, and outdated BIOS is available (1.13). When you update to this following https://help.ubuntu.com/community/BIOSUpdate does this improve the situation? For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

OK, after 3 days, even the most recent firmware still has this bug: /lib/firmware/iwlwifi-7265D-21.ucode I'm switching back to the 15.10 firmware which did NOT have this bug and we'll see if it still crashes: /lib/firmware/iwlwifi-7265D-12.ucode -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577957 Title: Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm sorry, I take that last comment back upstream is still working. I was just using the wrong kernel (4.6).

More information: It turns out that upgrading to the latest firmware and driver *still* does not solve the problem, so, not even the upstream version of the driver itself is aware of this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577957 Title: Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577957 Title: Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I tried to test 4.6, but that version is even *more* unstable than 4.4 the connection drops out consistently every couple minutes or so. Also, that version still uses the old firmware, so the driver hasn't yet been upgraded to master of the authors: ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577957 Title: Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577957 Title: Intel 7265D wifi firmware crashes on a Lenovo x1 carbon (3rd generation) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.6 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
