Lapic error causing real time to stop.

I would like to find out if there is a way to identify errors around Lapic.

A error would show something like this:

TIMER NAME: lapic; VARIOUSLY FOUND APIC FREQs: 20833247, 20833247, 20794250

Thanks,
Oz

If this does not give you the answer, you need to come back with some proper information, not just an unexplained snippet from dmesg.

regards

( Which kernel, which distro, which version Linuxcnc, what computer, full dmesg output, full Linuxcnc error output etc etc )

So Sorry,
Let me try again,

I'm using Debian 2.7.0.

Intel P35 with a Mesa 5i25

There is no Linuxcnc error.

Let me know if I'm missing something.

I am still very new to this.

Oz

Can you launch LinuxCNC from the command line so that any error messages can be observed?

Yes,
No error messages.

And loads but no enabling of the controller.

Oz

OK, but you are still just posting a snippet of dmesg, which seems to show that the 5i25 was discovered and initialised.
No error there.

Do a reboot with the card installed and then start Linuxcnc

Then do
dmesg > dmesg.txt and post the resultant dmesg.txt file as an attachment.

I am guessing you are saying the 5i25 is not enabled, so there should be something to indicate what happened and there should be an error as soon as the hal file tries to address the first 5i25 pin.

Are you sure real time is not working and its not just a hal/ini error of some kind?

You can take a look at the parameter motion.servo.last-period to see if things are running:

Machine --> Show Hal Configuration --> Watch --> Parameters --> Motion --> servo last period

This should keep changing if the servo thread is running (its value will be approximately CPU Clock rate /servo thread rate)

OK,

Here it is.

Oz

I dont see any errors, does LinuxCNC exit unexpectedly?
That is, what makes you think there is an error?

PWC,

There is servo thread running.

Ok,
What should I do next?
