Bug 212457

I upgraded the computer from fedora 33 to fedora 34 beta so the kernel messages disappear... sorry.

With the new release, with kernel 5.11.9-300.fc34.x86_64, the problem has not appeared.

Created attachment 296091 [details]
dmesg with out-of-tree VirtualBox drivers

problem appear again

Before the iwlwifi error appears, there are several warnings which are not related to iwlwifi. dmesg cannot even print all the messages since boot, because the printk ring buffer is not large enough.

- Can you reproduce this behavior without the VirtualBox drivers? Please see: https://www.kernel.org/doc/html/latest/admin-guide/tainted-kernels.html

- Can you make the printk ring buffer larger, by setting the kernel parameter 'log_buf_len' with a larger value? The default value in Fedora 34 is 256KiB. See:
https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html

after uninstalling virtualbox drivers...
i forgot to enlarge log_buf_len... in the next one

Thanks! This is much better.

Now, can you please try to reproduce this problem using the "vanilla" mainline kernel? Run the first two commands on this page to install it: https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories

Assuming it's not fixed in the mainline kernel, can you please attach dmesg for it?

dmesg showing the error with vanilla kernel 5.11.11-350.vanilla.1.fc34.x86_64

There is more than one vanilla repository; sorry for the confusion.

Could you please install and try "kernel-vanilla-mainline"? (The version will be 5.12.0-rc5 or later.)


With that kernel, could you run this command before suspend (when Wi-Fi works), and run it again after resume (when Wi-Fi is broken):

    lspci -xxxvvv

Please attach the output both times. Also please attach dmesg. Thanks!

I install the suggested kernel: kernel-5.12.0-0.rc5.20210331git2bb25b3a748a.181.vanilla.1.fc34.x86_64

Did this work in an earlier release of 5.11.x?

Unless it did — can you please try a vanilla build of the mainline kernel? (Is this still happening in 5.12 and/or a 5.13 snapshot?) It would need to be fixed there before any changes can be made to the stable kernel. Please see: https://www.kernel.org/doc/html/latest/admin-guide/reporting-issues.html

Thanks!

how can I test 5.13?

will the ones from https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories be valid?

It seems to be fixed with 5.15 please close.

let me try kernel-5.15.0-0.rc7.20211028git1fc596a56b33.56.vanilla.1.fc35.x86_64 for a few hours to close it :)

the bug is still here: "iwlwifi 0000:05:00.0: Error, can not clear persistence bit" in kernel-5.15.0-0.rc7.20211028git1fc596a56b33.56.vanilla.1.fc35.x86_64
:(

Maybe you need a new firmware too. I am using Fedora 35 with a mainline Kernel from https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories

just like me but again I hit the same bug: 
[10779.130581] iwlwifi 0000:05:00.0: Error, can not clear persistence bit

This week I will try a new card... The hardware may be broken :(

I can confirm this bug is still present in 5.15.0-2.ge9c94fc-default

the bug is still here with another card from another vendor, also ax200, using the latest kernel from fedora 35, 5.14.17-301.fc35.x86_64.

I have the same issue. Given my system and the info here I'm speculating its related to a combination of AMD Ryzen 3/4/5, Lenovo and ax200

(I have a Lenovo 13ACN05 with AMD Ryzen 5700U and ax200)

I dug around in the source code for iwlwifi, PCIe and ACPI, but I came up empty handed...

Does anyone have any suggestions for how to debug this to pinpoint the issue more accurately?

my cpu is also an AMD Ryzen 3 3200G...

Same issue here: (it has nothing to do with AMD) 
- Ubuntu 21.10;
- Kernel: 5.15.5-051505-generic;
- CPU: Intel® Core™ i7;
- ASUS motherboard.

I can confirm the same issue with Intel CPU:

Fedora 35
CPU: Intel(R) Core(TM) i7-5600U CPU
Kernel: 5.15.6-200.fc35.x86_64
DELL XPS13

Not 100% same scenario, but I'm getting the same error if I start my laptop running on battery and laptop-mode-tools is installed.

But not if I plug it up before. With the power cord, everything works fine.

Trying to reload the module once (and plugging in the power cord) does not work, I need to restart the laptop with the power cord attached.

Funny enough, uninstalling laptop-mode-tools fixes the issue (running on battery), although then the battery does not last much.

Quick update on my previous message, disabling power save on battery for wireless interfaces in laptop-mode-tools avoids the issue:

File /etc/laptop-mode/conf.d/wireless-power.conf, set:

WIRELESS_BATT_POWER_SAVING=0

And restart.

Not really :(

There is something else going on, as with the same config, most of the times the interface is not available after restart yet.

I'll keep investigating...

Eh, well, I guess this one kind of fell through the cracks and it's been a year now.

Anyone still seeing these issues?

working fine under newer kernels :)

Unfortunately, still occurring w kernels 6.2x and 6.5x (various distros tried, currently Fedora 38 Cinnamon), Ryzen 5 3500C on a converted Thinkpad C13 Yoga Chromebook running mrchromebox.tech latest firmware. Many noob apologies if I am in the wrong place, but I am trying to get to the bottom of this error for resolution's sake because I LOVE this hardware.
