FreeBSD 10.1-RELEASE Errata
Abstract
This document lists errata items for FreeBSD 10.1-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 10.1-RELEASE will be maintained until the release of FreeBSD 10.2-RELEASE.
Table of Contents
Introduction
This errata document contains "late-breaking news" about FreeBSD 10.1-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version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the "current errata" for this release.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 http://www.FreeBSD.org/releases/, plus any sites which keep up-to-date mirrors of this location.
Source and binary snapshots of FreeBSD 10.1-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 http://www.FreeBSD.org/security/ or ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/.

Open Issues
-
FreeBSD/i386 10.1-RELEASE running as a guest operating system on VirtualBox can have a problem with disk I/O access. It depends on some specific hardware configuration and does not depend on a specific version of VirtualBox or host operating system.
It causes various errors and makes FreeBSD quite unstable. Although the cause is still unclear, disabling unmapped I/O works as a workaround. To disable it, choose
Escape to loader promptin the boot menu and enter the following lines from loader(8) prompt, after anOK:set vfs.unmapped_buf_allowed=0 boot
Note that the following line has to be added to
/boot/loader.confafter a boot. It disables unmapped I/O at every boot:vfs.unmapped_buf_allowed=0
[2014-04-03 update] It has been reported that instability may be present on virtual machines running on other hypervisors, such as Xen or KVM.

FreeBSD/i386 10.1-RELEASE configured with a multi-disk ZFS dataset (mirror, raidz1, raidz2, raidz3) may crash during boot when the ZFS pool mount is attempted while booting an unmodified
GENERICkernel.As described in
/usr/src/UPDATINGentry20121223, rebuilding the kernel withoptions KSTACK_PAGES=4has been observed to resolve the boot-time crash. This, however, is not an ideal solution for inclusion in theGENERICkernel configuration, as increasingKSTACK_PAGESimplicitly decreases available usermode threads in an environment that is already resource-starved.Taking into account the heavy resource requirements of ZFS, in addition to the i386-specific tuning requirements for general workloads, using ZFS with the FreeBSD/i386
GENERICkernel is strongly discouraged.Warning: It is extremely important to take note that, by default, freebsd-update(8) will install the
GENERICkernel configuration, and as such, freebsd-update(8) consumers are strongly encouraged to avoid FreeBSD-provided kernel binary upgrades with such configurations.Note: Although there is slight change in how the crash manifests on FreeBSD/i386 between 10.0-RELEASE and 10.1-RELEASE, and given the date of the
/usr/src/UPDATINGentry, there is no evidence suggesting this is a regression between FreeBSD 10.0-RELEASE and FreeBSD 10.1-RELEASE directly. -
Due to an incompatibility between bsdconfig(8) and pkg(8) version 1.3, packages included on the FreeBSD dvd installer will not be recognized by bsdconfig(8).
To install packages from the
dvd1.isoinstaller, create the/disttarget directory, and manually mount thedvd1.isoISO:# mkdir -p /dist # mount -t cd9660 /dev/cd0 /dist
Note: Be sure to use the correct
/devdevice path for thedvd1.isoISO installer.Next, set
REPOS_DIRto the path of therepos/directory within the installer so pkg(8) will use the correct repository metadata.If using sh(1):
# export REPOS_DIR=/dist/packages/repos
If using csh(1):
# setenv REPOS_DIR /dist/packages/repos
Note: Keep in mind that
REPOS_DIRwill need to be set again after the current shell session is terminated, if continuing to use the packages provided on thedvd1.isoinstaller.Finally, bootstrap pkg(8) from the ISO, and install required packages:
# pkg bootstrap # pkg install xorg-server xorg gnome2 [...]

[2015-02-06] Affects binary upgrade users: The second phase of
freebsd-update install, the phase where the running userland is upgraded, fails on systems deployed withnss_ldapenabled in nsswitch.conf(5) when upgrading from 10.0-RELEASE to 10.1-RELEASE.
A workaround is to disable nss_ldap in
nsswitch.conf(5) prior to running freebsd-update
install to upgrade the userland, after which it can be
enabled again when the upgrade process is completed.
The problem is being investigated, and an Errata Notice is expected to be issued when a solution to the problem is identified.

[2015-03-31] Several reports were received regarding the QCOW2 FreeBSD virtual machine images crashing on boot. As result of this, these images have been removed from the FTP mirrors, and the hashes removed from
CHECKSUM.SHA256andCHECKSUM.MD5in theVM-IMAGES/directory on the FTP mirrors.
