1<!-- 2 FreeBSD errata document. Unlike some of the other RELNOTESng 3 files, this file should remain as a single SGML file, so that 4 the dollar FreeBSD dollar header has a meaningful modification 5 time. This file is all but useless without a datestamp on it, 6 so we'll take some extra care to make sure it has one. 7 8 (If we didn't do this, then the file with the datestamp might 9 not be the one that received the last change in the document.) 10 11--> 12 13<!DOCTYPE article PUBLIC "-//FreeBSD//DTD DocBook V4.1-Based Extension//EN" [ 14<!ENTITY % man PUBLIC "-//FreeBSD//ENTITIES DocBook Manual Page Entities//EN"> 15%man; 16<!ENTITY % authors PUBLIC "-//FreeBSD//ENTITIES DocBook Author Entities//EN"> 17%authors; 18<!ENTITY % mlists PUBLIC "-//FreeBSD//ENTITIES DocBook Mailing List Entities//EN"> 19%mlists; 20<!ENTITY % trademarks PUBLIC "-//FreeBSD//ENTITIES DocBook Trademark Entities//EN"> 21%trademarks; 22<!ENTITY % release PUBLIC "-//FreeBSD//ENTITIES Release Specification//EN"> 23%release; 24<!ENTITY % misc PUBLIC "-//FreeBSD//ENTITIES DocBook Miscellaneous FreeBSD Entities//EN"> 25%misc; 26]> 27 28<article> 29 <articleinfo> 30 <title>&os; 31<![ %release.type.snapshot [ 32 &release.prev; 33]]> 34<![ %release.type.release [ 35 &release.current; 36]]> 37 Errata</title> 38 39 <corpauthor> 40 The &os; Project 41 </corpauthor> 42 43 <pubdate>$FreeBSD: head/release/doc/en_US.ISO8859-1/errata/article.sgml 124312 2004-01-09 20:10:20Z bmah $</pubdate> 44 45 <copyright> 46 <year>2000</year> 47 <year>2001</year> 48 <year>2002</year> 49 <year>2003</year> 50 <year>2004</year> 51 <holder role="mailto:doc@FreeBSD.org">The FreeBSD Documentation Project</holder> 52 </copyright> 53 54 <legalnotice id="trademarks" role="trademarks"> 55 &tm-attrib.freebsd; 56 &tm-attrib.intel; 57 &tm-attrib.sparc; 58 &tm-attrib.general; 59 </legalnotice> 60 </articleinfo> 61 62 <abstract> 63 <para>This document lists errata items for &os; 64<![ %release.type.snapshot [ 65 &release.prev;, 66]]> 67<![ %release.type.release [ 68 &release.current;, 69]]> 70 containing significant information discovered after the release 71 or too late in the release cycle to be otherwise included in the 72 release documentation. 73 This information includes security advisories, as well as news 74 relating to the software or documentation that could affect its 75 operation or usability.

As a workaround, disable ACPI, using the <quote>safe 155 mode</quote> option of the bootloader or using the 156 <varname>hint.acpi.0.disabled</varname> kernel environment 157 variable. These problems are being investigated. For problems 158 that have not already been reported (check the mailing list 159 archives <emphasis>before</emphasis> posting), sending the 160 output of &man.dmesg.8; and &man.acpidump.8; to the 161 &a.current; may help diagnose the problem.</para> 162 163 <para>(9 Jan 2004) In some cases, ATA devices may behave 164 erratically, particularly SATA devices. Reported symptoms 165 include command timouts or missing interrupts. These problems 166 appear to be timing-dependent, making them rather difficult to 167 isolate.
