Hi Damien,

Yes I have.  I have a fairly basic system running (Linux, EtherLab, r8169, DLS ethercat) and those messages are continuous as long as the scanner is running.  I had been meaning to look into it, but since the ethercat communications were working fine I figured it was a low priority.  I'd be happy to test out your changes if you'd like independent verification.  The system is currently running but the hardware it's connected to is not being used for anything important for a little while.  Cheers,

Jon
