I'll do that before I go play with it again, to both machines. But I am finding it interesting that it can run for days at a time, as long as I am not running linuxcnc, but my uptime is usually under half an hour with it running. And it doesn't seem to care what particular gcode file its running. I do not know if the isolcpus=1 command was in the old /boot/grub/grub.cfg, but after running update-grub, its gone! Has some grub related update overridden that option, or is it now compiled into 2.6.32-122-rtai kernel? That may well explain a lot! I do not have backups of the /boot tree on either machine. My amanda recipes only include /etc, /home, lib/firmware, /usr/lib/amanda, and /usr/local. Can someone still on the 10.04-4 LTS release check that for me? Thanks.
