KNOWN ISSUES

See bugzilla.yoctoproject.org

382 - oprofile-server on PPC is built big-endian while oprofile-viewer on host system may built with little-endian, but oprofile-server and oprofile-viewer are not implemented to correctly handle conversion between host byte order and network byte order, so oprofile-server and oprofile-viewer may run into connection issue.

439 - No audio from the Blacksand board Front Channel auido jack. Workaround: run the following cmd: 'amixer sset "Front" 30 on'

467 - Issues building with Fedora 14, this distribution provided a version of make that is not compatible with the Poky build system, the workaround it to build a native version of make via the build system. Users of Fedora 14 will need to do a 'bitbake make-native' before running any other targets.

429 - Building poky from scratch with /opt/poky in your path cause host contamination issues, be sure that /opt/poky is not in your path if building from scratch

160 - The Emenlow Hardware gets stuck in the HW Reboot sequence and needs to be power cycled.

Zypper / RPM Issues 489/490/491 - Due to some archetectual difference between Zypper and RPM5.0, there are some compatibility issues that prevent zypper from working correctly. Packages can still be managed with the rpm commands.
