Since 4.19 WiFi card cannot be enabled after booting on battery, without power cable plugged in.

Once I plug the power cable in, I can turn WiFi card on and set the interface up.
It also continues to work after waking up from suspend, even without power cable.

This worked flawlessly with Liquorix 4.18.
Also it still works fine with Ubuntu's 4.18 kernel (both generic and lowlatency).

So I'm not sure if it is a problem with Liquorix build or 4.19 kernel in general.
Anyone has similar issues with 4.19?
Drivers maybe?

Try the latest kernel that was released last night, it has a fix for suspend issues with wifi / usb.

Do you mean liquorix 4.19.0-12.2, or the upstream Linux 4.20?

As for liquorix 4.19.0-12.2 (and today's 4.19.0-12.3) this issue is still present.

This is more a boot / power management problem. Suspend doesn't affect this issue.
