Because its also a devel machine, haveing 2 SSD's attached where it can 
build the target sw, there are often 1 minimum to as high as 4 ssh -Y 
logins. But only one in the last several days.

None of this is a huge showstopper unless it causes a huge latency to 
occur in the machine control. Normal is for the program if running, to 
take inventory of what the machine is doing and issue corrective actions 
every millisecond. I do not know that to be the case but if a part was 
being carved at the time, I'd imagine it would be damaged as this 
nominally 5 milliseconds means the machine is un-monitored for a part 
wrecking way too long.

I was hoping the time frame between these events might trigger an 
association memory from some of your folks.

[334858.869] (--) modeset(0): HDMI max TMDS frequency 225000KHz
[336658.866] (II) modeset(0): EDID vendor "ONN", prod id 257

That shows the interval between these events as thats the last line of 
the previous event and the first line of another.  And it seems to be 
fairly consistent. Something cron is doing might be one possibility.  It 
is a raspbian buster install as an armhf but could at some point be done 
as a full 64 bit install.  R-pi-4b, 2 G's ram.
