1 Introduction

This errata document contains ``late-breaking news'' about FreeBSD 4.9-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version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the ``current errata'' for this release.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 http://www.FreeBSD.org/releases/, plus any sites which keep up-to-date mirrors of this location.

Source and binary snapshots of FreeBSD 4-STABLE also contain up-to-date copies of this document (as of the time of the snapshot).

No active security advisories.

3 Late-Breaking News

Very late in the release cycle, a change was made to the HyperThreading (HTT) support on Intel® processors. HTT support is now enabled by default on SMP-capable kernels; as a result, the HTT kernel option is unnecessary and has been removed. The extra logical CPUs are always started so that they can handle interrupts, but are prevented from executing user processes by default. To enable the logical CPUs, change the value of the machdep.hlt_logical_cpus +href="http://www.FreeBSD.org/cgi/man.cgi?query=sysctl&sektion=8&manpath=FreeBSD+4.8-stable"> sysctl(8) variable from 1 to 0. This value can also be set from the loader as a tunable of the same name.

Some of the packages contained in the first CD-ROM depend on different versions of the +OpenLDAP packages, which cannot co-exist on the same host. One +manifestation of this problem is that it is not possible to install both the x11/gnome2 and x11/kde3 packages.
