There are worrying reports of filesystem corruption on ext4 in karmic.
Scott says:
12:36 < Keybuk> this whole ext4 thing is worrying me
12:36 < Keybuk> I just downloaded an iso image, md5sum didn't match
12:36 < Keybuk> downloaded it into an ext3 partition, matched just fine
12:59 < Keybuk> and I know mvo has seen bugs with corrupted .debs in
/var/cache/apt/archives
12:59 < Keybuk> which seems to imply its any file large enough to use lots of
extents
I'm opening this bug report so that this bug gets tracked & triaged for
karmic. If we're unable to isolate the issue, we should consider
rolling back to ext3 as the default filesystem in the installer.
