iwlwifi crashing on X1 Carbon 5th Gen "Microcode SW error detected"

On the new 5th Gen Lenovo X1 Carbon and Intel 8265 on a fresh Arch install iwlwifi keeps crashing the moment network is coming up. Happens on both core/linux-firmware 20170309.695f2d6-1 and aur/linux-firmware-iwlwifi-git 20160725.26a5c2a-1.

After it's crashing it's impossible to rmmod iwlmvm and iwlwifi, all netctl and ip commands are hanging, sudo isn't working and even shutdown isn't working.

Tried netctl and NetworkManager. Netctl sometimes work for a few minutes before it crashes, NetworkManager is chrashing after a few seconds.

Someone reported a bug with Intel 7265D card wich looks exactly the same. https://bugs.archlinux.org/task/53317

The firmware files for 8265 found in /lib/firmware are:
- iwlwifi-8265-21.ucode
- iwlwifi-8265-22.ucode
- iwlwifi-8265-27.ucode

Thanks for the tip. Now it's wrapped in a code tag.

Re: iwlwifi crashing on X1 Carbon 5th Gen "Microcode SW error detected"

@GenericNumber please help with the upstream bug report if you are able see Reporting_bug_guidelines#Upstream_or_Arch.3F for Arch's policy on upstream bugs.
If you need help applying a patch that upstream has requested for testing etc please ask.

Re: iwlwifi crashing on X1 Carbon 5th Gen "Microcode SW error detected"

I've encontered this bug and is very tricky, in the meantime while there is a working patch. You can detect which firmware was loaded and remove (make a backup) the loaded firmware so it fallsback to a older version. It worked for me.

$ dmesg | grep iwlwifi

[   10.131995] iwlwifi 0000:02:00.0: enabling device (0000 -> 0002)
[   10.132327] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7265D-26.ucode failed with error -2
[   10.132340] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7265D-25.ucode failed with error -2
[   10.132352] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7265D-24.ucode failed with error -2
[   10.132362] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-7265D-23.ucode failed with error -2
[   10.135536] iwlwifi 0000:02:00.0: loaded firmware version 22.391740.0 op_mode iwlmvm
[   10.156036] iwlwifi 0000:02:00.0: Detected Intel(R) Dual Band Wireless AC 7265, REV=0x210
....

In this case it loaded: /usr/lib/firmware/iwlwifi-7265D-22.ucode
Backup and remove this file.

It will load the previous version ( /usr/lib/firmware/iwlwifi-7265D-21.ucode), in this case, this version doesn't have the bug. I guess that should work on other iwlwifi versions like 8265

Re: iwlwifi crashing on X1 Carbon 5th Gen "Microcode SW error detected"

I also encounter this problem. this problem occurs if I don't turn off my WiFi before shutting down.
but if I turn off my WiFi before shutting down, there is no boot message like that.
I have tried to use the ucode as module and also compile it into the kernel, both of them show same problem. the message only disappear if the WiFi is turn of before shutting down. so I use systemd to automate the process.

I also have 7265D card and also couldn't connect to 5GHz band

Re: iwlwifi crashing on X1 Carbon 5th Gen "Microcode SW error detected"

@cortexalf the upstream bug report indicates it should be resolved in 4.14-rc1 have you tried 4.14-rc8 to test if it is?
