There are a small number of known bugs that users may run into with Ubuntu 9.04 RC which will be fixed before the final release. We have documented them here for your convenience along with any known workarounds.

For a full list of errata for Ubuntu 9.04, please see the Ubuntu 9.04 release notes.

When using the ext4 filesystem, accessing large files can trigger a kernel panic and filesystem corruption. The fix for this problem will be included in the final 9.04 release. Users installing from the Ubuntu 9.04 Release Candidate may wish to avoid this problem by using the default ext3 filesystem and converting it to ext4 after release. 348836.

The OEM setup mode is not usable in the Kubuntu release candidate. This will be corrected for the final release. 361665.

The mythtv frontend in mythbuntu fails to render fonts correctly when using video drivers other than the Intel or closed-source nVidia drivers. This issue is expected to be resolved for the final 9.04 release. 341898

原来可以从ext3格式转换到ext4格式啊？

这个早就不是新闻了。

打死我也不转，要么就重装。肯定超慢啊，partionmagic分区都慢死我了，何况还要格式化之类的，到时候还不一定能好

ubuntu自带的格式化，很快的啊！

ext3--->ext4不是早就能够实现了么，不过据说转换之后性能会有问题，建议直接备份之后格式化
