Hi,

Journalctl telles me;

Nov 04 00:48:58 manjaro kernel: INFO: task kworker/5:2:95545 blocked for more than 860 seconds.

Thanks for your advice :slight_smile:

The problem is this:

Disabling it will probably only hide the from, not solve it. The problem appears to be related to the r8152 kernel module and/or usb.
