--- Comment #8 from Maxim Usatov <maxim.usatov@bcsatellite.net> ---
I have kernel{arc_prune} stuck at 100% CPU with system completely unresponsive
on FreeBSD 13.3-RELEASE releng/13.3-n257428-80d2b634ddf0. Can reproduce every
time by doing rsync from internal ZFS NVMe storage to an external UFS SATA
drive attached via USB. Is there a hope of getting this fixed in 13.3 as well?
