Extremely slow boot

Hi all, I am getting this error on boot since about kernel 4.20.x in Fedora (does not happen in Ubuntu):

A start job is running for udev wait for Complete Device Initialization – 2.58 min

Hi @revolucion09 check this link, it can be related with your issue the last post was done for the user saifjsl (he is using fedora). Here is a bug report RHEL7 long boot time, systemd-udev-settle.service - Red Hat Customer Portal about same issue.

Either masking systemd-udev-settle.service or blacklisting blacklist i2c_nvidia_gpu work, but no idea about the consequences.

Blacklisting i2c + nvidia bumblebee leaves my system where I want it to be
