Hi,

I'm posting here to get some attension to 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=278726

I've been testing 14.1-BETA/PRERELEASE.

Short description:

FreeBSD kernel uses 100% CPU with "swapin"g.
It uses 100% CPU but no IOs occur.
This happens with arm64 while amd64 works fine.


Long description:

I use zfs with an external device and only when needed.
So, I don't have ENABLE_ZFS.

After booting the system, system operates fine.
After "zpool import <pool>", kernel starts spining.
"top" shows kernel is in "swapin" status.
On the other hand, no disk activities are happening.
"zpool expot <pool>" doesn't stop swapin activities

Hiro
