Roberto, I have experienced this same issue with 8.04 installed from the live CD - but it is occurring on EMC 2.2.6. I haven't allowed the upgrade to 2.2.7 to occur, but I did install all the critical & other apps.
I have found a work around - load EMC2 again! I only get the rtai_hal.ko file exists error the first time I try to run EMC after a reboot. If I shut it down and start it again, it loads. Here are the error messages I see after a reboot: http://pastebin.com/m12dbb0b6 Here is the dmesg list after a reboot: http://pastebin.com/m23c28ffb Here is the dmesg list after I load EMC, let it fail, close and re-open: http://pastebin.com/m71e7e99b (I'm still working on the unexpected real time delay on task 1) I hope that is helpful. I didn't report it before because I am very new to EMC and I thought I was doing something wrong. Oh, another random bit of information - this error also happens if I try to load emc-trunk using run-in-place. Alex On Fri, Nov 14, 2008 at 9:58 AM, Eric H.
