Thank you for the additional detail! It appears to be the case that having an APC surge supressor inline, despite it being labelled as gigabit-capable, was the cause of the CRC errors. I changed cables, and that not helping, I swapped in different APC units, and the errors persisted until I went straight from NIC to ONT. Now I've gone a couple hours without seeing an error, and haven't in fact seen one since the link came back up after the most recent change. I'm glad the driver stopped suppressing these errors, or I'd not have known the inline surge supression was a bit flaky. Thank you. --=20 Mason Loring Bliss mason@blisses.org They also surf, who only stand on waves. --KscbYT9j58UvY3Ip Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEEXtBZz1axB5rEDCEnrJXcHbvJVUFAmLduUcACgkQnrJXcHbv JVXKxQ/+JQ85ZD2m9ANWpXWmE8a7iAK81amwFZA/2DkDpsKRQJPPYpyAIDzCEv2m lKaWyfzGY5A0f5LerwMdEXEe5bMrLiXqc+gSZhPuNBfwFyOv3dN/NcTgGJxcshmX wLcaak0kD6EgZ/VBZuYxWwqOXZiGw3Adydg6FB5fQvT31H2bxxfajO3M/oPa7TTN I73QuIxIgWuS2Y8+0thgiLPVp5nvk5geRx72WZeaHwR2xt3dykMfKDR8q08YHROi q/fJpswouLHAISVjFZ3wNrJ27gpwXcfiFP5qCMccWw+vWNx1RolYmtopvroCAESh t7l7QxVXPbhjXFX0RGPzGmUgeYrmAmFY33dnu8MXuyqTCKlM6kTjxy4Db5jzUdio +WrWygxiM09x4oo5fIbnH/Ra4kq99LCtydnAyT3hWCwzlOQKsEXfI8DkVbv9U0HK 8x0DMU9Od41ktR/jt021JRJRZLHyKGtsvDzg077ps9qOQnPLsc7el4cdXfJYNS+d u6ZXCOQmU97rqWNQI2t9J3l6cK3lu9A0vEHpI1jrVMjewg+FEh+1Mv2Y+50zu7Wi eTYyVnjqP4vhddrMFDUcA4c6BAfDopetS3pjfyWlWb/aERQBlSkT5Bcy9m8a6/NA Vx4cWYNVX9gbSbnUjJt6k7vy8jRHTleNXRM/nKCUHAJswIsDinQ= =ywiO -----END PGP SIGNATURE----- --KscbYT9j58UvY3Ip--
