Hi Trendy
how did u enable it?
starting from scratch, adding PPPOE, then enable Banip, selecting some IPset sources, don't get further than:
: banIP runtime information
or from a command line;
/etc/init.d/banip enable
the git README has had a note about this... need to update the top post as it's tripped a few people up...
setting things up like this allows for packing in a wide range of packages... yet not bloating everybodys logs / performance with stuff they dont need to be running... much easier to turn on one or two things than to disable 25 
More to what @anon50098793 wrote already, I didn't start from scratch, as I had already a working banip from the previous installation. I had to enable it (service banip enable) after I upgraded.
@migube you are a genius... you've hit two birds with the one stone here...
after all my talk about disabling stuff out of the box... it seems vpn-policy-routing has snuk through the cracks... (doh!, thats the whole reason for disabling things that and two adblocks at the same time are defo nono dodo ) and seems like it might be behind some of @alpynz 's / mwan3 issues...
it was kinda unresponsive... ( to disables ) so alpy, best of you trash the package all together...
opkg remove --force-removal-of-dependent-packages vpn-policy-routing
reboot ( or full network restart ) might not hurt either...
onwards an upwards!
cheers will do and continue testing... MWAN3 2.10.0-1 seems happier but vpn policy rouitng will definetly be trying to do same thing ... was still seeing occasional LUCI hangs on config chnages to MWAN but hard to pin down...
ok... you have to make this... shoutout to DarkElvenAngel [thankyou], i used an alpine chroot on-device - /etc/init.d/ntop will set one up for you if you edit the variables at the top and start it... chroot CHROOTDIR, ( apk add dtc git make etc. ), git clone, make all, (i skipped this: make install), mkdir /run, cp argononed /usr/sbin/, cp argonone-shutdown /usr/sbin, cp argonone.dtbo /boot/overlays/ ( maybe run the setup-overlay.sh )... then likely reboot and run 'argononed' ( or add /usr/sbin/argononed & to your rc.local etc. )...

( as with most things build related, a few users need this, i'll look at integrating it (wrt.ini option and init.d script) into the build once sort out git versioning )
Thank you so much for looking into this. I have never done some of this stuff before but this is a great opportunity to learn.
I followed your explanation and the daemon is now running.
The issue is the I2C is still not working.
I have installed kmod-2c-core, i2c-tools but no i2c device appears in /dev .
Is there anything else i should be trying?

try removing: dtparam=i2c1=on ( keep: dtparam=i2c_arm=on line )
Turns out i was missing kmod-i2c-bcm2835.
Seems to be working now.
Thank you very much!
just a quick report to say testing seems all ok with this MWAN vers- no LUCI hangs after 2 days and routing down 3 wan links works as per expected. seems pretty stable.. 
I have issue with SQM. I get very stuttery movement in games. Now i installed the new package
rpi4.64-snapshot-23300-1.13.57-5-r14475-ext4-sys.img
SQM is off and game is working fine without any stutter.
please show
uci show sqm
and the speeds up / down from a speedtest with nothing using the network...
you can try the command
speedtest-ookla
uci show sqm

and one more thing when i was getting stuttery movement in game. Ping plotter was showing smooth pings. no packet loss whatsever
ok, not sure if adaption->default + overhead is normal? either way... this isn't build related... and there is likely something else going on...
make a separate thread so all the sqm experts will see it. ( you can link to the post above by clicking the diagonal-chain icon on the lower right of the post )
@anon50098793 what you did? after updating the pi4. All the packages installed automatically without doing anythings.
before i used to install all the packages one by one now they are already installed.
Thanks great 
fantastic to get feedback ( working even better ) from someone in the wild about the autorestore...
in my testing, it was just a tad unpredictable to make perma-default setting... so in future ( r145xx+ ) i'm disabling the 'apply' of this...
what this means...
But I recommend manually using the method below after firstboot is all finished, so you review / verify what package actions are to be performed...
MANUAL METHOD
Once sysupgraded.... from luci;
From the command line (alternative to luci method);
restorepackages.sh
restorepackages.sh run
#(or edit /autorestore.sh and run that yourself)

Has anyone tried USB boot to see if theres any perf increase?
Not sure if there would be.
http://www.jeffgeerling.com/blog/2020/im-booting-my-raspberry-pi-4-usb-ssd
https://www.jeffgeerling.com/blog/2020/raspberry-pi-usb-boot-uasp-trim-and-performance
wanted to but...
pros(for me): usb boot, particularly 'boot order' aka fallback when not present etc. also tftpboot
cons: current one works pretty well ( minus the above feature ), mmc so far seems to be the quickest...
need to keep this pi as common / bugfree as possible for the builds, and i've fried the primary uart pins... and without those i'm reluctant to mess around with the bootloader...
pretty sure the openwrt images will be fine... athough the default cmdline.txt would need to be changed after writing the image, preferably to PARTUUID= should work... come to think of it... there is probably a bit of stuff in preinit / init.d / lib-upgrade... that's likely hardcoded to mmcblk... so sysupgrade would be 'broken'
( edit: not as bad as i'd guessed )
[root@dca632 /usbstick 46°]# fgrep -r mmc /lib
/lib/preinit/79_move_config:BOOTPART=/dev/mmcblk0p1
only a few lines tho...
i think practically the newer firmware has bugfixes particularly for usb/video... so anyone with buggy usb or video behavior would have a good practical reason to take the plunge...
