As is to be expected at this stage of the release process, there are several known bugs that users are likely to run into with Intrepid Alpha 5. We have documented them here for your convenience along with any known workarounds, so that you don't need to spend time reporting these bugs again:

• When using manual partitioning and configuring crypt+LVM, the partitioning will fail in certain configurations. As a workaround, you can use the "Entire disk with encryption" install option. https://bugs.launchpad.net/bugs/251640

• The Intrepid 2.6.27-2 kernel fails to boot as a Guest under VirtualBox. This issue is expected to be resolved for Intrepid Alpha 6. https://bugs.launchpad.net/bugs/246067

• Resume from Suspend with the 2.6.27-1 and 2.6.27-2 kernel will cause the system to reboot/shutdown. This issue should be resolved with the 2.6.27-3 kernel which will be uploaded post Alpha5. https://bugs.launchpad.net/bugs/262423

• A list of known regressions regarding the 2.6.27 kernel has been assembled at https://bugs.launchpad.net/ubuntu/+bugs?field.tag=regression-2.6.27

• On Ubuntu systems, the "Shutdown" button in the Quit... menu does not shut down the system, but instead logs the user out. Investigation of this issue is ongoing. For now, please shut down from the log-in menu. https://bugs.launchpad.net/bugs/250506

• On Ubuntu systems, the default desktop theme is wrong. As a workaround, please select "Human-Murrine" (or another theme of your choice) in System ? Preferences ? Appearance. https://bugs.launchpad.net/bugs/256972

• The X.Org configuration file (/etc/X11/xorg.conf) still has InputDevice entries for the mouse and keyboard, but they are ignored now because input-hotplug is used. The keyboard settings come from /etc/default/console-setup, and to change them please use "sudo dpkg-reconfigure console-setup". After that, HAL and X need to restart.

• After upgrading to this version, some keys might misbehave in X. Please make sure you have set the keyboard model as Generic Evdev-managed keyboard in System ? Preferences ? Keyboard, in the tab Layouts. If some keys still have problems, please file a bug against xkeyboard-config, and provide the output of setxkbmap -print and xkbcomp :0 - both run in the Terminal.

• Memtest86+, accessible via the boot menu, falsely reports some memory as failing the test. Investigation of this issue is ongoing. http://launchpad.net/bugs/246412
