elapsed clocks between calls to the motion control

I found this in my bootmsg.txt

Is the any procedure to trouble shoot this?

[ 275.545143] In recent history there were
[ 275.545146] 1425380, 1663080, 1650830, 1686080, and 1857990
[ 275.545150] elapsed clocks between calls to the motion controller.
[ 275.545163] This time, there were 1715460 which is so anomalously
[ 275.545166] large that it probably signifies a problem with your
[ 275.545170] realtime configuration. For the rest of this run of
[ 275.545173] EMC, this message will be suppressed.

Hi

That is the tail end of the real time error message.

Run a latency test. If that is OK it is quite possible that you get this error once at startup of linuxcnc and then not thereafter.
Some systems seem to do this when there is a sudden load on resources but are fine for the rest of the session.

Alternately you could have a new problem you were not aware of.
( happened to me once, when the BIOS backup battery went dead, BIOS reverted to defaults and I lost all the settings I had made to turn off power saving, hyperthreading, fan temp sensing etc
took me a while to realise what was happening )
