Roberto, I suspect what is happening is that the real time kernel is not the default kernel and the errors you are seeing are a consequence of not having a real time kernel loaded. You can select the kernel on boot, on some systems you may need to hit escape while grub is loading in order to select the kernel. The real time kernels will have 'rtai' in the name.
To permanently change the default kernel, edit the file /boot/grub/menu.lst. I don't know why this has changed for HH, as far as what becomes the default kernel, but this question will continue to get asked until that is changed. Regards, Eric I have installed on my PC the Ubuntu 8.04 HH with EMC2 from the live cd from linuxcnc.org. After, i have updated my system to EMC 2.2.7 with the ubuntu update manager, so I have updated EMC2 and other 227 files (from critical update and other applications...). Now when I try to load EMC2 with sim configuration (but it happens with any configuration), the rtai doesn't be loaded with the following error: insmod: error inserting '/usr/realtime-2.6.24-16-rtai/modules/rtai_hal.ko' -1 File exists 4891 PID TTY STAT TIME COMMAND Stopping realtime threads Unloading hal components ERROR: Module rtai_math does not exists in /proc/modules ERROR: Module rtai_sched does not exists in /proc/modules ERROR: Module rtai_hal is in use by rtai_lxrt I don't know how it's possible, i have tryied to reboot the pc but nothing... I think that other applications use this rtai_lxrt but who is this??? ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
