 - Steps to reproduce
   

Applicable to all devices using the generic sysupgrade.

Seen on LEDE head.

To reproduce:

scp over a new .img file

upgrade it as "sysupgrade -v xyzzy.img"

While that's running, you'll be able to ping the router, but if you do an http connection to it, it will be reset.

What would be simpler would be doing a "/etc/init.d/network stop" just after killing off all services (including web servers).

This would make it easier to add scripting which auto-detects when the upgrade has completed by reconnecting after a reasonable wait (and retrying as necessary).
