Linux and Intel Corporation Wi-Fi 6 AX200

Problem with PCI Message Signaled Interrupts

Check the dmesg

I'm including my logs

Issues

Linux frozen for while and then crashed.. all after few hours in loop with 'pci=nomsi' and AX200 (iwlwifi driver).

How to fix

Get list of system apps on the device:

adb shell "echo 'apps:' && pm list packages -f | grep /system/app/ | sed 's/.*=/  - /'"

Remove application command

pm uninstall -k --user 0 app

echo $(ifconfig eth0 | awk '$1 == "inet" {print $2}') \
$(nslookup $(ifconfig eth0 | awk '$1 == "inet" {print $2}') | \
awk '{ print $4; exit }') $(hostname) >> /etc/hosts

Introduction

I'm working with Ansible and many of servers every day, so let me show you, how can waste less of your time! :)

What Ansible do?

Connects, runs, check, sends back, processes it, runs, checks, sends back and voila!
Connects... again... and again... and again...

What you can do to fix on node/remote server

Edit sshd config and disable UseDNS, it's mainly used only for logging and authentication. But.. only when you have set IgnoreRhosts in your config. So who doesn't know, should use it with clean mind. Because this has truly so far with security. :)

How to debug Qpid Proton

If you need debug Qpid Proton, use these enviroments variables:

Log driver related events, initialization, end of stream

PN_TRACE_DRV = true # or 1

Log frames into/out of the transport

PN_TRACE_FRM = true # or 1
