When my computer wakes up from standby / suspend, there’s a small chance that instead of seeing the lock screen I get a black screen: The monitor turns on but the background is all black, I can see the mouse cursor and move it around but nothing more. When this happens I need to use Control + Alt + F# to switch to a different TTY where I login as root and use the reboot command to restart.
What’s notable is that when switching to any TTY, the screen is covered in error messages printed every second. I can’t even see what I type as they appear over my text without even generating a new line. The message always reads:
usb usb6-port3: config error
usb usb6-port3: Cannot enable. Maybe the USB cable is bad?
Linux used to do this since many years ago, back when I had a different motherboard and my OS was openSUSE Tumbleweed instead of Manjaro… however I don’t remember it ever crashing my system like it does now. I also see that message sometimes when restarting normally, right after the normal session shuts down but before the screen goes dark and the computer reboots.

This is the output of lsusb on a normal session after restarting: I don’t get which of them is supposed to be usb6-port3. I’m not aware of any connected USB device or port having any issues, everything works well under normal circumstances.
