I am a bit new to linux environment.

My Linux System is freezing when I am connecting to wifi dongle.

It works fine when I start the system without dongle, but the complete system hangs when I connect the dongle. And this freezing continues even when I disconnect the dongle. And it starts good if i disconnects it.

There are no logs generated on the issue but when i started to see on a different console using Alt+Ctrl+F3 I could able to see some logs beginning with RAX RSP RDX following by some hex-code. Can someone help me to resolve it.

Here is the log of event.

  • Run sudo dmesg -w in a terminal and then plug your dongle in. Post the output here. – JShorthouse Jul 30 '19 at 11:56
  • @JShorthouse I could not retrieve the records, the logs are being flushed as soon as I reboot the system – shiva Jul 30 '19 at 13:01
  • Everything in dmesg should also be logged to a file somewhere, I can't remember which file exactly but google will be able to help you. – JShorthouse Jul 30 '19 at 14:18
  • Hello @JShorthouse , Finally I generated the above log using script. The log gets freezed at the "assoc success". Please let me know if you have any solution – shiva Jul 30 '19 at 15:37
  • Sorry, my knowledge of these kinds of issues ends at finding the right log output. You'll have to google the error you've found or hope that someone else comes by. – JShorthouse Jul 30 '19 at 15:53

I also encounter the same situtation, not sure if it's too late to answer this question...

I solved this issue by disabling system-monitor of Gnome Shell Extension (I installed it by apt install gnome-shell-extension-system-monitor).
