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 ", kernel starts spining. "top" shows kernel is in "swapin" status. On the other hand, no disk activities are happening. "zpool expot " doesn't stop swapin activities Hiro
