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.

1. Introduction

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of this errata document actually distributed + with the release (for example, on a CDROM distribution) will be + out of date by definition, but other copies are kept updated on + the Internet and should be consulted as the “current + errata” for this release.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).

For a list of all FreeBSD CERT security advisories, see + https://www.FreeBSD.org/security/.

4. Open Issues

  • 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 errorneously states the + WITH_SYSTEM_COMPILER src.conf(5) + option is enabled by default, however this was disabled + prior to the final release build.

5. Late-Breaking News
