usability. An up-to-date version of this document should

<para>A system tunable has been added as of revision
<literal>r286584</literal> to make the
<literal>kern.kstack_pages</literal> tunable configurable
without recompiling the kernel.</para>
<para>To mitigate system crashes with such configurations,

prompt, after an <literal>OK</literal>:</para>
<screen>set kern.kstack_pages=4

<para>[2017-07-21] Due to a bug in earlier versions of
&man.clang.1; that is difficult to work around in the
upgrade process, to upgrade the system from sources via
buildworld to -CURRENT or &release;, it is necessary to
upgrade machines running 9.x to at least revision r286035,
or machines running 10.x to revision r286033. Source-based
upgrades from 10.3-RELEASE are not affected. This differs
from the historical situation where one could generally
upgrade from anywhere on earlier stable branches, so caution
should be exercised.</para>
</listitem>
<listitem>
<para>[2017-07-25] &os;/&arch.arm64; currently lacks
<acronym>EFI</acronym> real-time clock
(<acronym>RTC</acronym>) support, which may cause the system
to boot with the wrong time set.</para>
<para>As a workaround, either enable &man.ntpdate.8; or
include <literal>ntpd_sync_on_start="YES"</literal> in
&man.rc.conf.5;.</para>
</listitem>
<listitem>
<para>[2017-07-25] A late issue was discovered with
&os;/&arch.arm64; and "root on
<acronym>ZFS</acronym>" installations where the root
<acronym>ZFS</acronym> pool would fail to be located.</para>
<para>There currently is no workaround.</para>

<listitem>
<para>[2017-07-26] Note for those upgrading from 11.1-RC2 in
<application>VirtualBox</application>:</para>
<para>If system panics were experienced when upgrading from
11.1-RC1 to 11.1-RC2, and the <filename
role="package">emulators/virtualbox-ose-additions{,-nox11}</filename>
port was built locally as a resolution, the port will either
need to be rebuilt when upgrading from 11.1-RC2 to
11.1-RELEASE, or reinstall the package from the pkg(8)
mirrors using either:</para>
<screen> &prompt.root; <userinput>pkg install -f virtualbox-ose-additions</userinput></screen>
<para>or</para>
<screen> &prompt.root; <userinput>pkg install -f virtualbox-ose-additions-nox11</userinput></screen>
<para>To ensure the system does not panic after rebooting into
the updated kernel, it is recommended to disable the
<literal>vboxguest</literal> service in &man.rc.conf.5;
prior to rebooting the system if possible, or use
&man.pkg.8; to forcefully reinstall the package.</para>
<para>Systems being upgraded from 11.1-RC1 and earlier and
11.1-RC3 to 11.1-RELEASE should be unaffected.</para>
</listitem>
<listitem>
<para>[2017-07-27] The release notes erroneously state
revision <literal>r315330</literal> was sponsored by Rubicon
Communications, LLC (Netgate), when in fact this work was
done by Hiroki Mori independently.</para>
