Can you post a link to the entire dmesg list after you get a sserial error? (clearing the log before you start linuxcnc ) that is from a terminal window: sudo dmesg -C (clear the existing messages) (run linuxcnc until you get the sserial error) dmesg > log.txt and post log.txt I have the same issue and haven't been able to find a solution when I upgraded from 2.6.8 (?) to 2.7.0. First I updated the firmware on my 5i25 & 7i77. When I would run 2.7.0 I would get the following communication error. [ 87.831899] hm2/hm2_5i25.0: Smart Serial Comms Error: There have been more than 1 errors in 10 thread executions at least 200 times. See other error messages for details. [ 87.831908] hm2/hm2_5i25.0: ***Smart Serial Port 0 will be stopped*** I could jog anywhere from 2 seconds to 10 seconds and LinuxCNC would inform me of the error and shut down the 7i77 card. Only way to restart was to restart linuxcnc (that I found). The suggestion was that the 5vdc power supply powering the 7i77 was the problem potentially drawing too much current and lowering the voltage outside the 7i77 10% 5vdc range. I had been running the 7i77 from the PC through the 5i25 and over the cable and doing this for months. So, I first tried a 3amp 5Vdc wal wart (that I bought at some electronic store for too much$$$) and that didn't make a difference, then I bought a meanwell 5vdc power supply from jameco. I would say that the meanwell holds a steady 5.1Vdc, but that didn't work either. I did upgrade to 2.7.2 and that seemed to work better. At least I could jog longer or even run a program, but in the end, I still got the communication errors. When I did run the program, I had a 24vdc Ice cube relay (omron, idec type) for the lube pump and I had pulled it and didn't use it (too much lube). I wonder if that was an issue because I had forgotten I had it out, put it in the relay socket 2/3rds through a program, and at the END of my cnc program, I got the errors for the communication. In the mesa 7i77 manual, it does say that the 24vdc outputs do NOT need diodes, which I would normally use for a relay like this. Not sure I need it. Didn't add one, but I didn't think that would be the problem. Anyway, I have 2 harddrives that I swap between now and have the latest 2.6.11 (or is 10, I forget) on one harddrive and I can run that all day long. The 2nd harddrive has 2.7.2 and I don't run it at the moment because I don't feel comfortable that it will work. I had been meaning to troubleshoot more and re-install the 2.7.2 harddrive (and upgrade to 2.7.3), but haven't gotten round tuit it... One thing that I don't understand is that in the 2.7 upgrade instructions, there's a line item: 2.1.2. Hostmot2 dpll The Hostmot2 dpll??s default time constant has been changed from 40960 to 2000. The original value could occasionally lead to following errors when software like ntpd and ntpdate adjusted the rate of the linux CLOCK_MONOTONIC time source by up to 1000ppm in a single step. The new value allows the dpll to adjust to the change in the base period frequency without error. I don't know enough to know how that affects me, nor if that would be a problem (probably not), but it's a statement and I didn't do anything for it in the upgrade (like removing pet_watchdog). Anyway, I hope we can find a solution, I'm a bit perplexed by it... I can't look at it too much this week, but maybe next I can work on it more. Oh - one more thing is that I did have in my possession for about 1 week (thank you Peter & Katherine!) a brand new 5i25/7i77 combo and got the same errors. So, we're apparently doing something here, just not sure what it is. Regards, Mark ------------------------------

That seemed to work. It got rid of the messages when 2.7.3 starts up. So far so good, When I now F2 enable the machine I get a slew of "hm2/hm2_5i25.0: Smart serial card hm2_5i25.0.7i77.0.0 error = (4) Extra character" each with a ..."error = (13) Communication error" Looks like something is still mismatched? FWIW, it looks like the 5i25 is ver 1.43. Newer than it was, though not sure if that is the latest.
