1. Introduction

This errata document contains late-breaking news about FreeBSD 12.0-RELEASE Before installing this version, it is important to consult this document to learn about any post-release discoveries or problems that may already have been found and fixed.

Any version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the current errata for this release. These other copies of the errata are located at https://www.FreeBSD.org/releases/, plus any sites which keep up-to-date mirrors of this location.

Source and binary snapshots of FreeBSD 12-STABLE also contain up-to-date copies of this document (as of the time of the snapshot).

4. Open Issues

  • [2018-12-11] Some Intel® J1900 systems may hang on boot in UEFI mode. An observed workaround is to set kern.vty=sc at the loader(8) prompt. To have the setting persist after reboot(8), add kern.vty=sc to loader.conf(5).

    See PR 230172 for more information.

  • [2018-12-11] OpenSSL version 1.1.1 disables use of hardware cryptography accelerator cards provided by crypto(4) by default. Systems that have cryptography devices such as hifn(4), padlock(4), safe(4), and ubsec(4) currently will not take advantage of hardware cryptography offloading.

    It is currently unclear if an Errata Notice will be issued to re-enable use of crypto(4).

  • [2018-12-13] Due to the size of the base system of FreeBSD 12.0, the disc1.iso images for amd64 and i386 do not fit onto a 700 MB CD-ROM. As of FreeBSD 12.0-RELEASE, however, disc1.iso for these architectures can be written to a flash drive, or to a DVD.

    See PR 233989 for more information.

  • [2018-12-13] Some users have reported FreeBSD 12.0-RELEASE boot messages do not report CPUs other than CPU0. This is expected behavior introduced in r333334, and results in boot-time reduction.

  • [2018-12-13] The FreeBSD 12.0 release notes mention use of graphics/drm-stable-kmod and graphics/drm-legacy-kmod for modern graphics cards. These ports have been changed to a "meta port" in the Ports Collection, and will be renamed in the 2019Q1 quarterly branch, after which graphics/drm-kmod should be used instead.
