<!--
FreeBSD errata document. Unlike some of the other RELNOTESng
files, this file should remain as a single SGML file, so that
the dollar FreeBSD dollar header has a meaningful modification
time. This file is all but useless without a datestamp on it,
so we'll take some extra care to make sure it has one.
(If we didn't do this, then the file with the datestamp might
not be the one that received the last change in the document.)

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.</para>
<para>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out of date by definition, but other copies are kept updated on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 <quote>current
errata</quote> for this release. These other copies of the
errata are located at <ulink
url="http://www.FreeBSD.org/releases/"></ulink>, plus any sites
which keep up-to-date mirrors of this location.</para>
<para>Source and binary snapshots of &os; &release.branch; also
contain up-to-date copies of this document (as of the time of
the snapshot).</para>

<para>The implementation of the &man.realpath.3; function contains
a single-byte buffer overflow bug. This may have various
impacts, depending on the application using &man.realpath.3; and
other factors. This bug was fixed on the &release.branch; development
branch and the &release.prev; is not affected. However, this change
may not have been noted in the release documentation. For
more information, see security advisory

<para>The RAIDframe disk driver described in &man.raid.4; is
non-functional for this release.</para>
<para>ACPI seems to make some i386 machines unstable. Turning off
ACPI support may help solve some of these problems; see an item
in <xref linkend="late-news">.</para>
<para>An integer overflow could cause kernel panics on PAE-using
machines with certain memory sizes. This bug has been corrected
on both the <literal>RELENG_5_1</literal> and
<literal>HEAD</literal> branches. A workaround for this problem
is to remove some memory, update the system in question, and
reinstall the memory.</para>
<para>Attempting to write to an &man.msdosfs.5; file system that
has been upgraded from read-only to read-write via
<command>mount -u</command> will cause the system to lock up.
To work around this problem, unmount the file system first, then
mount it again with the appropriate options instead of using
<command>mount -u</command>.</para>

<para>&man.ipfw.4; should work correctly on strict-alignment
64-bit architectures such as alpha and sparc64.</para>
<para>The release notes should have stated that the
<filename>libthr</filename> library is built by default for the
i386 platform.</para>
<para>&os; &release.prev; includes some new boot loader scripts
designed to make booting &os; with different options easier.
This may help diagnose bootstrapping problems. These scripts
build on the existing Forth-based boot loader scripts (thus,
<filename>/boot/loader.conf</filename> and other existing loader
configuration files still apply). They are only installed by
default for new binary installs on i386 machines. The new
scripts present a boot-time menu that controls how &os; is
booted, and include options to turn off ACPI, a <quote>safe
mode</quote> boot, single-user booting, and verbose booting.
<quote>Safe mode</quote> booting can be particularly useful when
compatibility with a system's hardware is uncertain, and sets
the following kernel tunable variables:</para>
<programlisting>hint.acpi.0.disabled=1 # disable ACPI (i386 only)
hw.ata.ata_dma=0 # disable IDE DMA
hw.ata.atapi_dma=0 # disable ATAPI/IDE DMA
hw.ata.wc=0 # disable IDE disk write cache
hw.eisa_slots=0 # disable probing for EISA devices</programlisting>
<para>For new installs on i386 architecture machines,
&man.sysinstall.8; will try to determine if ACPI was disabled
via the new boot loader scripts mentioned above, and if so,
ask if this change should be made permanent.</para>
<para>The release notes should have mentioned that work on the
following features was sponsored by the Defense Advanced
Research Projects Agency (DARPA): OpenPAM, NSS support, PAE
support, various MAC framework updates, the GEOM disk geometry
system.</para>
