Sorry, I haven’t been paying attention, this was in response to the
thread with the virtio problem.  Yeah, I have been updating precisely
because of this; during the update, it seemed rather stable, even though
it had a lot do do, with a few ports compiling, hammer cleanup running
and something else.  Usually, it would have been gone at half the load.

It’s of course just a single sample, but I’ll definitely keep an eye on
it—as soon as I manage to boot it.
