This document lists errata items for FreeBSD 9.0-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 9.0-RELEASE will be maintained until the release of FreeBSD 9.1-RELEASE.
This errata document contains “late-breaking news” about FreeBSD 9.0-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version of this errata document actually distributed with the release (for example, on a CDROM distribution) will be out of date by definition, but other copies are kept updated on the Internet and should be consulted as the “current errata” for this release.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 http://www.FreeBSD.org/releases/, plus any sites which keep up-to-date mirrors of this location.
Source and binary snapshots of FreeBSD 9.0-STABLE also contain up-to-date copies of this document (as of the time of the snapshot).

In some releases prior to 9.0-RELEASE, upgrading by using freebsd-update(8) can fail. This issue has been fixed by a change in Errata Notice EN-12:01. For more information, see http://security.freebsd.org/advisories/FreeBSD-EN-12:01.freebsd-update.asc
[amd64, i386] FreeBSD 9.0-RELEASE includes several changes to improve resource
management of PCI devices. Some x86 machines may not boot or may have devices that no
longer attach when using ACPI as a result of these changes. This can be worked around by
setting a
loader(8)
tunable debug.acpi.disabled to hostres. To do this, enter the following lines at the loader
prompt:
set debug.acpi.disabled="hostres" boot
Or, put the following line into /boot/loader.conf:
debug.acpi.disabled="hostres"
A devctl(4) event upon arrival of a ugen(4) device has been changed. The event now includes ugen and cdev variables instead of device-name. This change can prevent the following devd(8) rule which worked in a previous releases from working:
attach 0 {
match "device-name" "ugen[0-9]+.[0-9]+";
action "/path/to/script /dev/$device-name";
}
This should be updated to the following:
attach 0 {
match "subsystem" "DEVICE";
match "type" "ATTACH";
match "cdev" "ugen[0-9]+.[0-9]+";
action "/path/to/script /dev/$cdev";
}
The FreeBSD 9.0-RELEASE Release Notes should have mentioned that SSM (Source-Specific
Multicast) MLDv2 now uses ALLOW_NEW_SOURCES and BLOCK_OLD_SOURCES record types to signal a join or a leave by
default. This conforms RFC 4604, “Using Internet Group Management Protocol Version
3 (IGMPv3) and Multicast Listener Discovery Protocol Version 2 (MLDv2) for
Source-Specific Multicast”. A new
sysctl(8)
variable net.inet6.mld.use_allow which controls the behavior
has been added. The default value is 1 (use ALLOW_NEW_SOURCES and BLOCK_OLD_SOURCES).
9.0-RELEASE fails to configure an interface specified in the
rc.conf(5)
variable ipv6_prefix_IF
when the interface does not have a corresponding ifconfig_IF_ipv6 variable. This problem will be fixed in
the future releases. To work around this problem on 9.0-RELEASE, add an ifconfig_IF_ipv6 line for each
interface specified in ipv6_prefix_IF as the following:
ipv6_prefix_em0="2001:db8:1:0 2001:db8:2:0" ifconfig_em0_ipv6="inet6 auto_linklocal"
In 9.0-RELEASE the FreeBSD USB subsystem supports USB 3.0 by the xhci(4) driver. However, a bug that could prevent it from working with a USB 3.0 hub has been found and fixed after the release date. This means 9.0-RELEASE and prior do not work with a USB 3.0 hub. This problem has been fixed in HEAD and will be merged into the 9-STABLE branch.
