Unfortunately, I cannot provide precise version information beyond that I was attempting to update 10.3 stable. I had just completed the installkernel step and had rebooted. I'm getting what appear to be kernel segfaults and if the system boots to multiuser, I see lots of "failed to write core file" messages. At one point, I saw a message indicating a required 'authdistd' (auditdistd?) user did not exist and that I should look at /usr/src/UPDATING, which says nothing about auditdistd or authdistd. I tried putting the old kernel back but the symptoms persist. HELP!!!!! Fortunately, this is a secondary server, not one of my primarie= s. This is a place where I have very little experience. In my recollection, this step has always gone smoothly. What now? Thanks! --P0QSTQkfkI9ftBMXgllVv5lB3vuhQVehA-- --Qpu34gTmOjnSHaXAlwXFHPKfGHpCtWqQA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCgAGBQJX++0OAAoJEOoml8Ul4D7WxucP/0agDuVhM03Dy7rYszXYFV3f Mjxgnswk3pV8A95j1cH0D2qA16fJHobSvGZYLXcKwwxfpU8ovY8HjB63ZSarSNtE yUXVVVnqnn6TotLbvfbZ+RO4bSMyt9TPK+ITyZTCz94Fz7PwVXbv8PyNEsb3jUgr YLQHy5rpQvP9C3Wj2qaQC+qKRT6mEdHduQRonCqOwS0nHyxqmsFU1uSJ4l/FkwKI vIDGzjcnM4w8qsly4AkVd6yHnBans0jCvBwcWzyhYO0l9tk/7jwS1Ss1luZS8cIj azsD4FIk/4xycC5OSZg+U1QqctpgNLYEZVZsU+ZUiDGcND2Qdjh5G3BHGGhvAxRr LzYFgF74Vm7PelfscJ7wfUyILTrXC26CkZdsfRX0Xkcngi+cI4+fyHyPtcCpXI1H iffS2LLhN+G0U6BcA2cOkKRj7CIFTMxcDuY6+wdw1c9i7tjaZb6Zu4P3Q0g2vdp7 ybguF8GOl4CU3/RFBm5jUtQfpeyRBz1QkWEtuAO9f0kRb+R1c99D0KdDtnFjsLrn GcxzQWuWZu5nFjUeT7BqpIjKcU6r0Vfe29ZkZtN/o0XeSOqQxXGveVVOx+BQtWbj Js/YGn3kSHUcF92msD+sh4ndZBjcnScDpkBGLAckVpwcbBn0N8LMk/GUtHtl3Gvv sYrYjFEaC0cdLDdhc337 =4lwO -----END PGP SIGNATURE----- --Qpu34gTmOjnSHaXAlwXFHPKfGHpCtWqQA--
