Bug Description

When I disconnect my AC adapter or run `sudo tlp bat` to switch to battery mode my wifi stops working. Reconnecting the AC adapter or running `sudo tlp ac` returns the wifi adapter to a functioning state.

I use the default TLP configuration without modifications and at first I was thinking that this is a bug in TLP. The FAQs already have an entry about this and state that this is due to the "kernel driver does not implement power saving properly" [1]. This is why I'm reporting the issue here.

I'm using Ubuntu Disco and I remember this working in previous Ubuntu versions / kernels. This happened on kernel 5.0.0-15-generic but also on the 5.1.5-050105-generic mainline kernel.

Below is a snippet of /var/log/syslog at the moment of switching TLP to battery mode. Battery mode was activated at 11:25 and AC mode was re-activated around 11:27.

Please let me know if this is actually the right place to submit this bug report and whether I can provide more information.

Can you please run 'apport-collect 1830883' in a terminal to attach relevant logs and system information to this bug?

It's likely you'll need to get support from Intel for this issue since it is a firmware crash, but one thing you should check is that you have the newest firmware available for your hardware. I can point you at the specific file once you've attached your system information, but if you know which file you need you can find it here:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/

If you still have this problem with the newest firmware available, you should report the bug here:

Thank you for helping out, Seth.

`dmesg | grep firmware` shows me

> [ 1360.174032] iwlwifi 0000:02:00.0: Loaded firmware version: 36.9f0a2d68.0

so I assume that my /lib/firmware/iwlwifi-8265-36.ucode is being used. That's also the latest version in the linux-firmware git tree.

Is there anything else I can check before publishing another bug report at kernel.org?

That does appear to be the latest firmware. There's some information about debugging and reporting bugs here:

https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging

There are some things there to try, but given that this appears to be a firmware crash I don't know that they will be of much help. Your best bet is to follow the instructions there to report a bug for the developers at Intel to look at.

Hi Seth,

we debugged this and we found out that d0i3 was not disabled in iwlwifi. This is a kind of power saving thing that requires integration with the platform / kernel that should be enabled only for specific platform. Not something that should be enabled in a distribution kernel.

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/net/wireless/intel/iwlwifi/iwl-drv.c?h=linux-5.1.y#n1670

In mainline, it is disabled by default.
Not sure what happened here.

It's also disabled by default in our kernels.

https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/disco/tree/drivers/net/wireless/intel/iwlwifi/iwl-drv.c#n1643

And the 5.1.5-050105-generic kernel which was tested and also has the
problem is an unmodified upstream build. My system has nothing specified
for the module parameter in /etc/modprobe.d, and I get Y from
/sys/module/iwlwifi/parameters/d0i3_disable.

@jnns, is it possible you've done something to your system to change the
module parameter? Could have been by adding it in in /etc/modprobe.d or
changing the kernel command line (cat /proc/cmdline). Not sure what else
might be changing it.

Dear Seth, dear Emmanuel,

please excuse me for having opened this ticket. Indeed, I found a configuration which (among other things) activated d0i3 that I copied and pasted verbatim from a blog post.

Sorry for causing such a mess. Although I'm thankful for your time and helping me fix my configuration.
