FreeBSD/i386 installed on ZFS may crash during boot
when the ZFS pool mount is attempted while booting an
unmodified GENERIC
kernel.
A system tunable has been added as of revision
r286584
to make the
kern.kstack_pages
tunable configurable
without recompiling the kernel.
To mitigate system crashes with such configurations,
choose Escape to loader prompt
in the
boot menu and enter the following lines from loader(8)
prompt, after an OK
:
set kern.kstack_pages=4 boot
Add this line to
/boot/loader.conf
for the change to
persist across reboots:
kern.kstack_pages=4
[2017-07-21] Due to a bug in earlier versions of clang(1) that is difficult to work around in the upgrade process, to upgrade the system from sources via buildworld to -CURRENT or 11.1-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.
[2017-07-25] FreeBSD/arm64 currently lacks EFI real-time clock (RTC) support, which may cause the system to boot with the wrong time set.
As a workaround, either enable ntpdate(8) or
include ntpd_sync_on_start="YES"
in
rc.conf(5).
[2017-07-25] A late issue was discovered with FreeBSD/arm64 and "root on ZFS" installations where the root ZFS pool would fail to be located.
There currently is no workaround.
[2017-07-26] Note for those upgrading from 11.1-RC2 in VirtualBox:
If system panics were experienced when upgrading from
11.1-RC1 to 11.1-RC2, and the emulators/virtualbox-ose-additions{,-nox11}
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:
#
pkg install -f virtualbox-ose-additions
or
#
pkg install -f virtualbox-ose-additions-nox11
To ensure the system does not panic after rebooting into
the updated kernel, it is recommended to disable the
vboxguest
service in rc.conf(5)
prior to rebooting the system if possible, or use
pkg(8) to forcefully reinstall the package.
Systems being upgraded from 11.1-RC1 and earlier and 11.1-RC3 to 11.1-RELEASE should be unaffected.
[2017-07-27] The release notes erroneously state
revision r315330
was sponsored by Rubicon
Communications, LLC (Netgate), when in fact this work was
done by Hiroki Mori independently.
[2017-08-09] The release notes stated the ruptime(1), rwho(1), and rwhod(8) utilities have been marked "deprecated", however this change was reversed in 12.0-CURRENT.
The other utilities mentioned in the entry in the release notes, however, are unchanged.
[2017-11-06] An issue with FreeBSD virtual machines with
vagrant was discovered that
affects the VirtualBox where the
virtual machine will not start on the initial boot invoked
with vagrant up
.
The issue is due to the virtual machine
MAC being unset, as FreeBSD does not provide
a default Vagrantfile
.
It has been observed, however, that a subsequent
invocation of vagrant up
will allow the
virtual machine to successfully boot, allowing access via
vagrant ssh
.
