Wifi does not load after upgrading

VenceBiri · 2017-10-07 10:22:46

Hello everyone,

After upgrading this morning, I was not able to load iwlwifi and my wireless card is not recognized.
The related part of dmesg is :

[   19.680045] iwlwifi 0000:3d:00.0: Failed to load firmware chunk!
[   19.680850] iwlwifi 0000:3d:00.0: Could not load the [0] uCode section
[   19.681728] iwlwifi 0000:3d:00.0: Failed to start INIT ucode: -110
[   19.681740] DMAR: DRHD: handling fault status reg 3
[   19.681743] DMAR: [DMA Read] Request device [3d:00.0] fault addr ffcc0000 [fault reason 06] PTE Read access is not set
[   19.702690] iwlwifi 0000:3d:00.0: Failed to run INIT ucode: -110

ip link gives the following :

[biri 12:17:49 ~] ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/ether dc:4a:3e:14:ca:62 brd ff:ff:ff:ff:ff:ff

I fear that the new linux firmware does not take into account my wireless card. There is also something strange at boot with "IRQ 17" which is disabled

Finally this is my lspci

I do not know how to fix it. I try reinstalling iwlwifi, even downgrading linux-firmware but without succes

Thanks a lot for your feeback

Post the output of pacman -Qm ... wondering if you need to rebuild a module not in the linux kernel package.

Thanks for the feedback.
This is the result of pacman -Qm

[biri 10:51:43 ~] sudo pacman -Qm
[sudo] Mot de passe de biri : 
glxinfo 8.3.0-1

During boot I also see this line :

I don't know if it is related...

I will check the DMAR. dmesg | grep DMAR gives me this :

I check the DMAR pb.

IOMMU has been enabled by default, and it's not as "defaultable" as initially hoped. Add
intel_iommu=off
to your kernel parameters.

but I don't know how to do that.

Suggested solution was in the second post of the thread I linked in post #3.

Hello,

Final post : It is solved !
As stated by "Ioqs" : it was indeed the intel_iommu pb. It fixes a lot of error at startup.
I follow this link to fix kernel parameter.

Thanks a lot to the Archlinux community (archlinux is the best linux distrib, by far )

(and I don't know how to set this post as [SOLVED]...)
