AMD-VI Page Fault device 2 and wifi

quick rant/story

Ok so Im here from Linux Mint, I tried the only one that I could get working effectively with wifi was LM XFCE version in compat mode, I think the Cinnamon Main and Debian suffer from the same problem when it comes to wifi.

trying to move away from win10

rant/story over

system:
AMD FX 8320 eight core black edition 125watt
Gigabyte 970A-D3P v2 motherboard bios v3 (FC)
Radeon RX 550 4gig
adata 800 SSD 500gig MBR mode
Western Digital HDD 1 TB MBR mode
Toshiba HDD 1 TB MBR mode
USB wifi adapter MediaTek 2.4ghz/ 5ghz
Gaming Headset G933

Under the LM distro's keep getting

AMD-VI Page Fault device 2

I believe this is related to the via technologies USB 3 controller

because when you punch up

lsusb

i get returned with

USB 1.1 Linux Foundation
USB 2 Linux Foundation

but nothing for USB 3 (is there a USB 3 Linux Foundation) controller ?

will the DeVuan Live usb or the desktop installer, auto setup the wifi adapter during installer?

I know Devuan is not really meant for noobs but it is that or Artix Linux and I have played with aptitude / synaptic more than pacman.

does .gdeb packages work on devuan?

intended install type is

drive 0
- win10 120gig
- Devuan / 120gig
drive 1
- windows stuff
drive 2
- Devuan /home


sorry if my questions are all over the place

and i did read head-on-a-sticks suggestion about making sure backports were on from this thread

Yes there is a usb3.0 hub.

lsusb ... (snipette)
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

You may require a newer "kernel" and "firmware" from backports for the devices of your motherboard.

This usb3 read out from my box is running on kernel

5.8.0-0.bpo.2-amd64 #1 SMP Debian 5.8.10-1~bpo10+1 (2020-09-26) x86_64 GNU/Linux

Also the microcode for AMD64 processors may help too.

I think you can put the module for wifi on a separate memory stick for use during the install process but I can't remember how I did it when I was using Devuan ascii2.1 and upgrading to Devuan Beowulf3.0.

I also used the git download and install linux-firmware method shared in the other post.
I hope this helps you.

Can you be more specific? An exact model designation would be nice. Or you could open a terminal and run dmesg -w then plug the device in and post any new terminal output that appears afterwards.

I think that error message is related to IOMMU rather than your wireless device. Try adding iommu=soft as a kernel command line parameter to remove those errors: https://askubuntu.com/questions/805008/ … page-fault

Please post the full, exact output of lsusb (with the device plugged in). Thanks.

You probably just need firmware for it but we need to know the chip ID first.
