FreeBSD 11.2-RELEASE Errata

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

[2017-07-25] 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.

[2017-11-06] 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.

[2018-06-21] An issue had been discovered late in the release cycle where removing ZFS vdevs from a pool under certain conditions would cause a system crash when zfsd(8) is enabled in rc.conf(5).

At present, it is believed to be limited to removal of a mirror vdev from a pool consisting of multiple mirror vdevs.

See PR 228750 for more information and updates as the issue is investigated.

[2018-06-26] An issue had been discovered late in the release cycle where a system crash could occur after installing emulators/virtualbox-ose-kmod from upstream package mirrors via pkg(8).

Building emulators/virtualbox-ose-kmod from the ports(7) collection has been observed to work around the crash.

See PR 228535 for more information.

[2018-06-26] It was discovered after the releng/11.2 branch was tagged for FreeBSD�11.2-RELEASE that a few device drivers were missing from the hardware page. The missing drivers, alc(4), cxgbev(4), liquidio(4), and mos(4) were added to the 11-STABLE hardware page.

[2018-06-26] The URL to the instructions for source-based upgrades in UPDATING incorrectly points to a page that no longer exists. The correct URL is https://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html.

[2018-06-27] The announcement email for FreeBSD�11.2 incorrectly states the ocs_fw(4) driver had been added; this should have stated ocs_fc(4).

[2018-06-28] An issue had been reported after the release of FreeBSD�11.2 with x11/nvidia-driver installed from the upstream package mirrors via pkg(8).

Building x11/nvidia-driver from the ports(7) collection has been reported to resolve the issue.

See PR 228536 for more information.

[2018-10-18] A FreeBSD system with a custom kernel configuration excluding NFS on 10.x did not explicitly require the krpc option to be included when booting via ZFS-on-root and, for example, setting MODULES_OVERRIDE="zfs opensolaris" in the kernel configuration.

In 11.x, however, krpc is explicitly required if the kernel configuration excludes NFS.
