[arm-allstar] dmesg output

[Roger Coudé]

Doug,
If I use more than one PI at one location, I need an ethernet  hub, a new fan, and a second power supply in the box. 
We have many sites and using a single PI would be cost effective, we are talking about thousands of dollars.
I have heatsink and fan everywhere, so the turbo mode is something I can try.
The site that gives the more error messages is a running with a 3B+
I will try with turbo mode.
Today we are in an emergency situation, two submarine cables feeding "Iles de la Madeleine" islands were cut by the last storm.
The islands lost telephone and internet, one of the reason why we have so many radios in order to keep RF links possible.

Roger,

That is a kernel message that I have never seen before.

At the cost of a Pi I am not sure why you would try to run three nodes on
one but that is a user choice. Here I never run more than two and most of
my 13+ are on one. It also adds to redundancy to have it more spread out.

That being said you really need to run in Turbo mode on the Pi and in that
case of course use a heatsink and a fan.

I doubt that the three FOB's would draw anywhere near the maximum USB
current so not sure why that is concerning you.

Another thing to consider is the 3B+ which has a little higher speed in
turbo mode and also would work better in your case using WIFI rather than a
wired connection. The reason is that starting with the 3B+ the WIFI does
not share USB bus. Wired does on all Pi's and adds to congestion when using
USB in a heavier way as you are. The 3B+ also has 5G WIFI which is a better
choice.
