<p>This document lists errata items for FreeBSD 7.2-RELEASE, containing significant
information discovered after the release or too late in the release cycle to be otherwise
included in the release documentation. This information includes security advisories, as
well as news relating to the software or documentation that could affect its operation or
usability. An up-to-date version of this document should always be consulted before
installing this version of FreeBSD.</p>

<p>This errata document for FreeBSD 7.2-RELEASE will be maintained until the release of
FreeBSD 7.3-RELEASE.</p>

<p>This errata document contains &#8220;late-breaking news&#8221; about FreeBSD
7.2-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.</p>

<p>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example, on a CDROM distribution) will be out of date by definition, but other copies are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 &#8220;current errata&#8221;
for this release. These other copies of the errata are located at <a
href="http://www.FreeBSD.org/releases/"
target="_top">http://www.FreeBSD.org/releases/</a>, plus any sites which keep up-to-date
mirrors of this location.</p>

<p>Source and binary snapshots of FreeBSD 7-STABLE also contain up-to-date copies of this
document (as of the time of the snapshot).</p>

<p>[20090501] Some machines do not recognize the i386 disc1 as bootable and fall through
to booting off the next boot device. All affected machines did see the other discs as
bootable. As a workaround, you can boot using the bootonly or livefs CDROM and then swap
in disc1 once <a

starts.</p>

<p>[20090504] A lock handling error has been found in interaction between <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">malloc</span>(3)</span></a>
implementation and threading library. When a multi-threaded process calls the <a

<span class="CITEREFENTRY"><span class="REFENTRYTITLE">malloc</span>(3)</span></a>
function in another thread, it can cause a deadlock in the child process. An Errata
Notice to fix this problem is planned after the release.</p>

<p>[20090505] A bug was found in the <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=bce&sektion=4&manpath=FreeBSD+7.2-stable"><span
 class="CITEREFENTRY"><span class="REFENTRYTITLE">bce</span>(4)</span></a> driver. This
prevents it from working with the <a

in the LACP (IEEE 802.3ad Link Aggregation Control Protocol) mode. An Errata Notice to
fix this problem is planned after the release.</p>

<p>[20090507] A bug was found in the <a

 class="CITEREFENTRY"><span class="REFENTRYTITLE">fxp</span>(4)</span></a> driver. This
would cause poor TCP performance when TSO is enabled, and the receiver has a smaller MSS
than the interface MTU setting. To workaround this issue, one can disable TSO by using <a

<code class="OPTION">-tso</code> parameter (per interface basis) or setting <code
class="VARNAME">net.inet.tcp.tso</code> to <tt class="LITERAL">0</tt> (globally on the
system). An Errata Notice to fix this problem is planned after the release.</p>

<p>[20090608] An issue was found in the <a

 class="CITEREFENTRY"><span class="REFENTRYTITLE">bge</span>(4)</span></a> driver that it
can cause a system panic upon reboot with heavy network traffic. A fix has been committed
to RELENG_7 (r192127).</p>
