2 Late-Breaking News and +Corrections

+ +

[20070116] The release notes should have mentioned that a separate ISO image has been +created with readable documentation files. It contains renderings of the documention for +all supported languages; the last several FreeBSD releases only contained English +documents due to space limitations.

+ +

[20070116] Some versions of the release announcement contained an incorrect manual +page reference for the GELI disk encryption subsystem. The correct manual page is +geli(8).

3 Security Advisories

No advisories.

4 Known Problems and Solutions

No issues.

[20070116] As mentioned in the release notes, the +arcmsr(4) driver +was updated for FreeBSD 6.2-RELEASE. Some isolated crash problems were noted after this +update, although the driver in general tends to work quite well for many testers, and it +seems to be “better” in general in terms of functionality and supported +hardware. Users having problems may wish to consider backing out the driver update or +installing a version of this driver directly from Areca. Further investigation is continuing into these +issues.

+ +

[20070116] FreeBSD 6.2-RELEASE has been diagnosed with kernel bug related to +UNIX-domain sockets. A patch for this problem has been committed to HEAD and RELENG_6, and is +a candidate for an errata patch to RELENG_6_2 after further testing.

+ +

[20070116] Systems with very heavy network activity have been observed to have some +problems with the kernel memory allocator. Symptoms are processes that get stuck in +zonelimit state, or system livelocks. One partial workaround for this problem is to add +the following line to /boot/loader.conf and reboot:

+ +

+kern.ipc.nmbclusters="0"
+

+ +

Other workarounds have been discussed on the freebsd-current@ +and freebsd-stable@ mailing lists.
