Couple of things I see in your fstab.
- Your line for swap looks like this:
UUID=82582173-f957-4a03-b3b5-289447c2726d swap swap defaults,noatime,discard 0 1
but AFAIK (and the way it is on my desktop) it should look like this:
UUID=82582173-f957-4a03-b3b5-289447c2726d none swap defaults 0 0
- Then this line:
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
can be safely removed. I read about it not too long ago here: Manjaro Wiki page about `/etc/fstab` needs corrections
