So, for anyone who may be impacted by this later, this is how I solved it. The goal is to put those in your /boot/loader.conf vfs.zfs.vdev.trim_on_init=3D0 vfs.zfs.trim.enabled=3D0 At least until the patch is released. When I booted up, my system was constantly crashing, so I booted in single user mode. If you mount your / partition rw now, it will crash. I had to: zpool destroy tank (tank is my zpool name here) mount -o rw zroot/ROOT/default / Then, put the lines above in your /boot/loader.conf. reboot! Should be set. After reboot, your zpool should be there because the destroy command was done when the FS was read-only so the changes have been done in memory only. Thanks.
