fstab woes

Greetings,
I recently installed 12.3 after using 11.4 for years. When I migrated my fstab all hell broke lose.
Any device that was not attached would hang the system which didn't happen ion 11.4. Previously, if I connected a device, it would automount according to my fstab settings. How can I do the same in 12.3? Also 2 of my 3 phones are not recognized at all in 12.3 but are still recognized if I boot to 11.4

Below is the fstab. All the commented lines are the lines that work in 11,4 but makes 12.3 hang.
