I could confirm it again with the default Ubuntu Kernel. I was downloading a compilation of files with Bittorrent while the battery went out. There was no problem afterwards and the files seem to be downloaded fine later on but I got errors. So I started a rehash of the compilation and it found around 40 defective chunks which needed to be redownloaded. Afterwards the file check works fine so I guess the problem might have something to do with crashes/blackout in combination with ext4.
There is no problem that some recently saved data is gone after a crash but at least it should be recognized through the journal and marked as such.
