My first Red Hat system defaulted to no-DMA for IDE disks. (Yes,
that was a long time ago.) With that setup, it was simple to generate
lots of lost timer interrupts: just keep the disk busy doing reads.

AFAIK peer associations do require authentication configured correctly.
I ask because after following this thread, I noticed that NTP running

Using another NTP server isn't hard on Windows, in fact it is dead

Evandro,
Remember, enable/disable auth has nothing to do with authentication
itself, just whether new associations can be mobilized if no
authentication is used. In your case a symmetric passive association was
apparently mobilized and began sending mode-2 packets just as if a
