Slow showdown/reboot

I have a newly rebuilt EOS Plasma system with btrfs on my nvme stick with the normal subvolumes. I also have an SATA SSD where I store videos, music, and VM images/ISOs so between rebuilds I don’t have to mess with them.

I have those EXT4 partitions on the SSD mounted at the / level in their own directory.

I’ve notices a lot delays in the shutdown portion of the reboot. It seems related to 2 of those 3 partition. It takes 1 minute before the shutdown completes. The countdown shows the count/1 min 30 sec. So it’s completing before the timeout, but it’s always 1 minute.

Not sure how to fix this. My fstab is below:
