Category: General LinuxCNC Questions
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.
