Comment 287 for bug 1667750

I was getting similar freezes with HP ENVY x360 Convertible 15 running OpenSUSE Leap 15.2.
This laptop model doesn't come with an RJ45 (LAN) port so I use a Type C USB ethernet adapter. And it was exhibiting the same problems, after some time it would just fail to work and initially I thought it was the NetworkManager.
For me even running the command 'ip add' would lock up, yet most other commands and even the desktop manager would still be working fine. But I couldn't get network back or even switch to WiFi. Basically every time this happened I had to restart the laptop.

Anyway, after going through the accounts here and other sites I found one which suggested that the issue could be with power management suspending the USB device.

So I added the particular USB to TLP black_list to prevent it from being suspended and so far I've gon 24 hrs without the lockup.
