iwlwifi failed to load firmware chunk

Hi all,

Every so often (maybe once every 10 boots) I boot up and have no wifi. "netctl-auto list" shows nothing, and "ip link" shows the wifi card as down. The only way I've managed to fix it is rebooting. Usually one reboot is suficient, sometimes it takes two. This is on a Lenovo Thinkpad x220 laptop.

According lspci, the card is:

 Intel Corporation Centrino Advanced-N 6205

This is the dmesg log when it's not working:

# dmesg|grep iwlwifi

I know it happens on battery, I don't know whether or not it happens when plugged in (it's pretty rare either way, which may make it impossible to diagnose in which case I'll live with it until I replace this laptop in 6 months or so).

Any ideas much appreciated!

Re: iwlwifi failed to load firmware chunk

Random ideas:
Try to move away every /lib/firmware/iwlwifi-*-6.ucode file (will likely be 6000g2a or 6000g2b, but idk) and see what happens.
Since you mentioned "battery", there've been reports about issues w/ the thinkpad_acpi module. Check whether it's loaded, whether it does something and in doubt try to blacklist it.

Re: iwlwifi failed to load firmware chunk

Hi Seth,

Do you mean to move those files when the problem occurs, or move them now (while wifi is working) and see what happens? I have

iwlwifi-105-6.ucode  iwlwifi-135-6.ucode  iwlwifi-2000-6.ucode  iwlwifi-2030-6.ucode  iwlwifi-6000g2a-6.ucode  iwlwifi-6000g2b-6.ucode

Also, I'm not sure how to tell if thinkpad_acpi does something. The module is loaded.

Thanks,
Lefty

Re: iwlwifi failed to load firmware chunk

Move them away and then reboot - the idea is to try the *-5 versions.
As for thinkpad_acpi, look at dmesg and suspicious messages from the module as well as about battery and acpi.

Re: iwlwifi failed to load firmware chunk

Thanks again for your help. I tried moving all of the *-6.ucodes into a new subfolder in /lib/firmware, and the problem persists. When I boot and have no wifi, I tried bringing the interface up:

# ip link set wlp3s0 up:
RTNETLINK answers: Connection timed out

I checked rfkill:

#rfkill
ID TYPE      DEVICE                   SOFT      HARD
 1 wlan      phy0                unblocked unblocked

And based on your suggestion I checked dmesg for thinkpad_acpi messages:

# dmesg|grep thinkpad_acpi
[   32.968669] thinkpad_acpi: ThinkPad ACPI Extras v0.26
[   32.968671] thinkpad_acpi: http://ibm-acpi.sf.net/

[   32.974452] thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver
[   32.974452] thinkpad_acpi: Disabling thinkpad-acpi brightness events by default...
[   32.977294] thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is unblocked
[   32.977826] thinkpad_acpi: Standard ACPI backlight interface available, not loading native one
[   32.982913] thinkpad_acpi: battery 1 registered (start 40, stop 80)
[   32.982979] input: ThinkPad Extra Buttons as /devices/platform/thinkpad_acpi/input/input5

I'm not seeing anything obvious in those outputs, the only real error I get is the iwlwifi "failed to load firmware chunk" message.

Any other ideas what might be causing this?

Re: iwlwifi failed to load firmware chunk

I'm not sure whether iwlwifi parses subdirs - ensure it's not trying to load the same firmware version.

Re: iwlwifi failed to load firmware chunk

Ah, good point. I moved all the -6.ucodes to a completely different directory (in my homedir), and unfortunately I still randomly get the error every 5 or so boots.
