99 <para>&os;/&arch.i386; installed on ZFS may crash during boot
100 when the ZFS pool mount is attempted while booting an
101 unmodified <literal>GENERIC</literal> kernel.</para>
103 <para>A system tunable has been added as of revision
104 <literal>r286584</literal> to make the
105 <literal>kern.kstack_pages</literal> tunable configurable
106 without recompiling the kernel.</para>
108 <para>To mitigate system crashes with such configurations,
109 choose <literal>Escape to loader prompt</literal> in the
110 boot menu and enter the following lines from &man.loader.8;
111 prompt, after an <literal>OK</literal>:</para>
113 <screen>set kern.kstack_pages=4
116 <para>Add this line to
117 <filename>/boot/loader.conf</filename> for the change to
118 persist across reboots:</para>
120 <programlisting>kern.kstack_pages=4</programlisting>
124 <para>[2017-07-21] Due to a bug in earlier versions of
125 &man.clang.1; that is difficult to work around in the
126 upgrade process, to upgrade the system from sources via
127 buildworld to -CURRENT or &release;, it is necessary to
128 upgrade machines running 9.x to at least revision r286035,
129 or machines running 10.x to revision r286033. Source-based
130 upgrades from 10.3-RELEASE are not affected. This differs
131 from the historical situation where one could generally
132 upgrade from anywhere on earlier stable branches, so caution
133 should be exercised.</para>
137 <para>[2017-07-25] &os;/&arch.arm64; currently lacks
138 <acronym>EFI</acronym> real-time clock
139 (<acronym>RTC</acronym>) support, which may cause the system
140 to boot with the wrong time set.</para>
142 <para>As a workaround, either enable &man.ntpdate.8; or
143 include <literal>ntpd_sync_on_start="YES"</literal> in
144 &man.rc.conf.5;.</para>
148 <para>[2017-07-25] A late issue was discovered with
149 &os;/&arch.arm64; and "root on
150 <acronym>ZFS</acronym>" installations where the root
151 <acronym>ZFS</acronym> pool would fail to be located.</para>
153 <para>There currently is no workaround.</para>
157 <para>[2017-07-26] Note for those upgrading from 11.1-RC2 in
158 <application>VirtualBox</application>:</para>
160 <para>If system panics were experienced when upgrading from
161 11.1-RC1 to 11.1-RC2, and the <filename
162 role="package">emulators/virtualbox-ose-additions{,-nox11}</filename>
163 port was built locally as a resolution, the port will either
164 need to be rebuilt when upgrading from 11.1-RC2 to
165 11.1-RELEASE, or reinstall the package from the pkg(8)
166 mirrors using either:</para>
168 <screen> &prompt.root; <userinput>pkg install -f virtualbox-ose-additions</userinput></screen>
172 <screen> &prompt.root; <userinput>pkg install -f virtualbox-ose-additions-nox11</userinput></screen>
174 <para>To ensure the system does not panic after rebooting into
175 the updated kernel, it is recommended to disable the
176 <literal>vboxguest</literal> service in &man.rc.conf.5;
177 prior to rebooting the system if possible, or use
178 &man.pkg.8; to forcefully reinstall the package.</para>
180 <para>Systems being upgraded from 11.1-RC1 and earlier and
181 11.1-RC3 to 11.1-RELEASE should be unaffected.</para>
185 <para>[2017-07-27] The release notes erroneously state
186 revision <literal>r315330</literal> was sponsored by Rubicon
187 Communications, LLC (Netgate), when in fact this work was
188 done by Hiroki Mori independently.</para>
192 <para>[2017-08-09] The release notes stated the
193 &man.ruptime.1;, &man.rwho.1;, and &man.rwhod.8; utilities
194 have been marked "deprecated", however this change
195 was reversed in 12.0-CURRENT.</para>
197 <para>The other utilities mentioned in the entry in the
198 release notes, however, are unchanged.</para>
202 <para>[2017-11-06] An issue with &os; virtual machines with
203 <application>vagrant</application> was discovered that
204 affects the <application>VirtualBox</application> where the
205 virtual machine will not start on the initial boot invoked
206 with <literal>vagrant up</literal>.</para>
208 <para>The issue is due to the virtual machine
209 <acronym>MAC</acronym> being unset, as &os; does not provide
210 a default <filename>Vagrantfile</filename>.</para>
212 <para>It has been observed, however, that a subsequent
213 invocation of <literal>vagrant up</literal> will allow the
214 virtual machine to successfully boot, allowing access via
215 <literal>vagrant ssh</literal>.</para>
