The main difference is that now it's 100% reproducible and I've never seen
corruption bad enough so I could not delete files without doing fsck first.

Here is pseudo output from fsck on ext3 filesystem after these problems
appeared:

Pass 2:

Bunch of these:

Invalid HTREE directory inode $NUMBER
$PATH/$FILE
Clear HTree index<y>?

and these:

Problem in HTree directory inode $NUMBER: block #$NR has bad max hash

Pass 3:

Bunch of:

Entry '$FILE in $PATH ($NUMBER) has a non-unique filename.
Rename to $FILE~0<y>?

Happily the files/directories affected was only the recently written from the
kernel from marex tree.  I haven't seen file content to be corrupted (that
doesn't mean there weren't any corruptions) but it seems they are not so likely
as directory tree corruption.
