If anyone else - like me - has tried updating the kernel this morning and figured out wifi with an intel card was broken: It seems they broke the iwlwifi driver [1] and here [2] is the patch to fix it.

Good to know. I've been using the rc releases for a bit without issue but will likely run into that immediately when upgrading.

I just got a thinkpad x1 carbon and have similar issues with the intel chipset for wifi and audio with newer kernels as well. Only thinkpad over ever had issues with .

  I have the same notebook (2019 edition) with Arch linux; everything is fine except audio, which won't work (basically the mic). Since I run every week or second into trouble after upgrading, I already thought about changing the distribution to something more stable, like Ubuntu/Debian. But I doubt my mic will work there :-(
  - GTP 7y ago
    Probably is just a config issue: for some reason this morning the wrong mic was selected as default and the update may have played a role since I don't remember changing it myself, but a quick look at pavucontrol solved the problem. PS: I'm using Arch Linux on a Lenovo too, but not a thinkpad.
    - ktpsns 7y ago
      Unfortunately, it is not. I already tried various kernel modules to support (i.e. detect) the hardware. Apparently, there is a reason why Arch chose some specific compiler flags for the kernel. I don't really want to start building my own kernel (there's a reason I chose Arch, not Gentoo).

If this is yours (Thinkpad X1 Carbon Gen 7), there's a very recent fix that you can find there. It's a bit of a hassle, but should work across more than just Arch based distros

  I'm also pretty disappointed with x1c7 Linux compatibility. I'm using Ubuntu 19.10 and it's not a smooth ride. I wish Lenovo had a Dell Sputnik like Linux support. Ubuntu 20.04 have been said to have better support.
ChristianBundy 7y ago
You may already do this, but bugs like these are the reason I usually recommend having two kernels. The "oh crap did the latest release break X" is a lot easier to test if you can just reboot into the LTS kernel.
- Spivak 7y ago
  Isn't that basically what every distro does these days by keeping 2+ kernels and a rescue kernel around?
  - ChristianBundy 7y ago
    Is there somewhere I can read more about that?

  Pretty sure these are different issues. The iwlwifi issue was introduced very recently with a security fix, as described by phoronix. I was running kernel 5.6-rc6 for some testing recently and it didn't have this issue.

  - kitotik 7y ago
    It is for me on 5.6-rc7. Tried as both a module and built in.
    - bavell 7y ago
      Really hope that's the case for me as well. I've been experiencing unrecoverable gpu hangs on my i915 Skylake chip with recent kernels (5.2-5.5).
      - kitotik 7y ago
        Yeap, same here. 5.5 was especially buggy for me, with frequent hangs while under heavy load. So far so good on 5.6.

I've been trying to convert people to various flavors of Linux for 20 years now and the usual showstopper is wifi not working at all, or at least without a ton more fiddling. Interesting to see that some things haven't changed. Trying to be constructive here, might it be because automated testing can't easily test things that touch the "real world"? Or is it due to some sheer number of possible wifi hardware implementations? Or both? (I really wish the vast majority of wifi antennas were hooked up directly to a generic SDR at this point)
- freedomben 7y ago
  If you are pushing your new converts to install/update to bleeding edge kernel releases, you're really doing them a disservice and setting them up for failure.
  - pmarreck 7y ago
    Over the course of 20 years? I’ve seen this issue from attempting an old Red Hat mainstream distro on an old Thinkpad years ago to any one of a number of Ubuntu or other distro install attempts over the years
- gsnedders 7y ago
  > Trying to be constructive here, might it be because automated testing can't easily test things that touch the "real world"? The Linux kernel still has embarrassingly little automated testing, and what is done is largely done by third-parties.

    That’s... actively stupid at this point

Being worried about the current trajectory of macOS, I’ve been thinking more and more about Linux and imagining how far it must have come since I last used it in the early 2000s. Reading things like this really dampen my enthusiasm for trying Linux again.
- macawfish 7y ago
  My sense is that this kind of thing is typical for newer versions of the Linux kernel. Most people don't run the latest kernel release, and for day-to-day applications, running an older, more stable version of the kernel won't effect anything. I quit MacOS a little over 10 years ago now. I used to be a huge Mac fan, even subscribing to MacAddict magazine and frequenting the Mac Rumors website. It was a cult and I have absolutely no regrets leaving. Especially now that Bitwig runs on Linux, what would I ever need a Mac for? I'm using Arch Linux and it's the most stable operating system I've ever used. I've gone more than 4 years with the same installation. Thanks to the Arch wiki I now have working knowledge of things like systemd and how to compile kernel modules. These things really aren't nearly as scary as they sound. I didn't learn about them by reading the longwinded `man` pages... I learned about them from the Arch wiki!

    > I'm using Arch Linux and it's the most stable operating system I've ever used. lol (from an arch user)
    - macawfish 7y ago
      Okay the lol is warranted... but in a certain way I'm serious: Ubuntu and MacOS were always changing things for me whenever I upgraded. Arch doesn't make any systemwide configuration changes. If some package has backwards-incompatible changes, I deal with those one at a time, but there's none of this "oh we rearranged the entire organizational structure of your root directory surprise!!!" stuff. And because I'm always getting the latest stable versions of things, bugs often disappear magically, rather than lingering on until the next major upgrade. And yeah I mean you gotta follow some key rules, like never install anything without the `u` flag, etc.

For what it's worth, I've been using 5.6 since early rc's in Fedora 32 pre-release for many weeks, and haven't had a problem with Intel Dual Band Wireless AC 8260. So not all Intel wireless is affected. Fedora 32 looks to be on-schedule for an April 21 release, pending release blocking bugs getting fixed up by then; and it will be shipping with Linux 5.6.
