New Install of LCNC,Debian12 dumping core

Hi
Pleases help.  I am trying to do a fresh install on an old computer and router system, but I am getting this error message: rtapi_app: caught signal 11 - dumping core.
This is what I get when I start LCNC from command line:
linuxcnc
LINUXCNC - 2.9.4
Machine configuration directory is '/home/aaron/linuxcnc/configs/Joe's-router'
Machine configuration file is 'Joe's-router.ini'

Strange.

Perhaps a corrupt ISO or install is to blame?

Try redownloading and reinstalling the official 2.9.4 ISO.

linuxcnc.org/iso/linuxcnc_2.9.4-amd64.hybrid.iso
www3.langdonstaab.ca/iso/linuxcnc_2.9.4-amd64.hybrid.iso

Hopefully that should fix it.

Make sure secure boot is disabled first!


While you are in the BIOS setup, also turn off turbo and powersaving features.

Set the cooling profile to max performance or active.


Also, Windows installations sometimes leave behind system partitions that don't always get erased when installing Linux.

Try removing all traces of Windows.

However, sometimes a system can't boot Linux without a Windows system partition there for some reason, it's all quite strange.

But secure boot is pretty much always bad.

iopl() is a system call required to gain access to privileged resources.
It is unclear whether the user has attempted an install from the Linuxcnc ISO or from a vanilla Debian install with a self built kernel or via package manager. Neither is it clear whether this is a RIP install of Linuxcnc or via a package.
If the OP can clarify these items and if self installed give a source for the instructions or elaborate on the process this would be great.

Blindly giving advice such as "reinstall" or redo this or that is the advice that is very common to the "Windows Ecosystem". As ethical Linux users it is far better to establish what the actual issue is and then make recommendations.
Even if one does suspect a corruption of the installation media it would be of great value to suggest, and advise the user how to, check that the ISO is a good download.
Tommy's advice regarding rebooting is a good suggestion regarding a previously "hung" Linuxcnc session.

So once we establish the user's method of install we can hopefully forment a solution.

Agreed.


However, non-Windows OSes can also benefit from clean installs.

Especially on Mac, installing apps leaves leftover gunk and lauch daemons.

Linux is better because apt purge exists, but it's not 100% perfect either.

Some programs (like Java) still create cache directories and stuff.

But checking the hash of big file is ssoooo sloooowwwww.....

Thanks for all your replies. I managed to do it by deleting all the partitions via the live usb (including one that I didn't recognize). Then reinstall using the whole disk. Sorry for doing it the windoze way!
Thanks again

Those partitons were left behind by Windows.

You have to fight Windows with Windows!
