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version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the ``current errata'' for this release.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).

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 (28 Oct 2003) Very late in the release cycle, a change was made to the HyperThreading +(HTT) support on Intel® processors.
