Alder Lake and soft updates don't seem to get along. After several crashes, all VFS related, I disables soft updates and, several hundred port builds later, not a single panic. If you have had problems with an Alder Lake system and have soft updates enabled, try turning them off. See tunefs(8) for details. Must be done after a stand after a single user boot before the file system is mounted RW. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683 --000000000000c320fc05e797e187 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable
