So, no, I was wrong. Changing the order made the rules apply. I simply removed

Yet none of those IPs are blocked, I tried with a server of mine, it gets added
to the list but is not blocked.

Hi,
I've been trying to install NetBSD/amd64 7.0 and 6.1.5 as a virtual machine
using Linux's kvm, and it led to panic while extracting sets:

A backtrace might help:

seems related to the virtio driver.
So I found this PR:
https://mail-index.netbsd.org/netbsd-bugs/2015/12/15/msg043768.html
Reducing the memory for the virtual machine allowed to install the OS
can I proceed in order to help debug this issue? kvm is a very popular
virtualization system on Linux and recently took over Xen regarding overall
performances, many cloud providers are using it.
Thanks,

I know, right? And yes results are identical with differents bs values.
I've tried a bazillion NFS options on the clients (TCP, UDP, {r,w}size from

to 64k...), tried many OSes as a client, the NFS results are consistent,
always between 20

Understood. Thanks again for your feedback!

For each subset, first column is the amount of data written (from 64K to 4M)
and first row is the block size.

FWIW, some ddb output (ddb is triggered by hitting + on domU's console):

Any idea how to get some valuable information to help tracking down this
awful behaviour?

Can you get into ddb?
unfortunately no, the system hangs but does not panic, it just becomes unusable.

anymore, but the server still replies to ICMP and does not panic. I waited for
about 4 hours to see if the operations would proceed but they didn't.
