Progress report, Sam. I had one hell of a time with the 12.04.2 LTS install, seems they have some new, undocumented way to carve(read fsck up) a new /etc/resolv.conf link at every reboot, and it was writing a blank file, so I couldn't get past the router to get online. The gui tools to adjust that never asked for a sudo password, so they couldn't fix it even if you entyered known good config data. Finally solved by copying my existing resolv.conf to the new install and doing a chattr +i on it. My post to the ubuntu list has a thin cloud of smoke questioning the genius that decided to screw with that. Anyway, the xenomai version of LCNC is now alive and well, with a few hiccups along the way, like it took a total reboot to actually make me a member of the group xenomai, but after that, and manually removing libgl- dev so the mesa versions would install, and its apparently all working. Worst case base thread latency is nominally 14.6 u-secs, and servo thread is about 17 u-secs. However, the xenomai kernel has no parport module, so even in RIP mode, the std sherline3axis will bail out at startup. Sim works fine. Would the isolcpus argument to the kernel improve that? AFAIK that hasn't been done (yet). That, and the parport issue, and I believe it could run my mill just as well as its being run now. I left the latency- test running for over an hour and saw no SMI glitches. Some glitches (or changes) in the build of the xenomai kernal I think, my dmesg|grep xenomai was a very short list, with the last 8 lines of the NewRTInstall page 2 listing went missing, and 2 lines of usb discovery replaced them. So, progress I think, promising even. Thanks for the boot in the butt to get me moving. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
