OK. So I think everyone is in agreement that the Pi4 LinuxCNC distribution
should be pulled and replaced with one that has a number of changes along with
an instruction note that the Pi4 to run LinuxCNC _must_ have forced cooling.
So what is? Where is?
1. SpeedStep
2. C1 states > 1
3. cool and quiet etc etc
We now know where isolcpus=1,2,3 but I'm not really clear why 1,2,3 instead of
1. And on boot my RPi4 still tells me Core 0 isn't available so there's
something else weird too.
[ 0.789877] kvm [1]: Error, CPU 0 not supported!
The major difference from the stock config.txt verses the one Sam posted is:
force_turbo=1
Don't think this has an issue to do with processor speed.
#disable_overscan=1
These three along with the force turbo will require heatsink and fan?
gpu_freq=600
over_voltage=6
arm_freq=1800
This is also now active. Not sure what it does either but this link suggests
it shouldn't be commented out like it is on the default LinuxCNC Pi4
distribution.

Finally I have, but at the moment I'm not using this, and I'll have to pull
that expansion card if I want to install a heatsink so I can comment this out.
# MCP2515 CAN interface
dtoverlay=mcp2515-can0,oscillator=12000000,interrupt=25
For now the Lawicel CANUSB is adequate for what I'm doing with CAN bus.
I've attached the dmesg log in case there's something else that might show
other issues.
