This document lists errata items for FreeBSD 11.0-RELEASE, + “®” symbol.
This document lists errata items for FreeBSD 11.0-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.
This errata document for FreeBSD 11.0-RELEASE will be maintained until the release of FreeBSD 11.1-RELEASE.
This errata document contains “late-breaking news” about FreeBSD 11.0-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.
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version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the “current errata” for this release. These other copies of the errata are located at https://www.FreeBSD.org/releases/, plus any sites which keep up-to-date mirrors of this location.
Source and binary snapshots of FreeBSD 11.0-STABLE also contain up-to-date copies of this document (as of the time of the snapshot).

An issue was discovered with Amazon® EC2™ images which would cause the virtual machine to hang during boot when upgrading from previous FreeBSD versions. New EC2™ installations are not affected, but exisiting installations running earlier releases are advised to wait until the issue is resolved in an Errata Notice before upgrading. An Errata Notice to address this is planned following the release.
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,
chose 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
A bug was diagnosed in interaction of the
pmap_activate() function and
TLB shootdown IPI
handler on amd64 systems which have PCID
features but do not implement the INVPCID
instruction. On such machines, such as SandyBridge™
and IvyBridge™ microarchitectures, set the loader
tunable vm.pmap.pcid_enabled=0 during
boot:
set vm.pmap.pcid_enabled=0 boot
Add this line to
/boot/loader.conf for the change to
persist across reboots:
To check if the system is affected, check dmesg(8) for PCID listed in the "Features2", and absence of INVPCID in the "Structured Extended Features". If the PCID feature is not present, or INVPCID is present, system is not affected.
vm.pmap.pcid_enabled=0
The Release Notes erroneously states the
WITH_SYSTEM_COMPILER src.conf(5)
option is enabled by default, however this was disabled
- prior to the final release build.
