I have just tested this with a new kernel. And the issue doesn't arise
with 2.6.35.7-vs2.3.0.36.33! So it is definitely a kernel bug, most
likely in ext4.
This really needs to be documented and stressed on the pages with
download links. Hashify feature causes total data corruption with
2.6.30.10-vs2.3.0.36.14-pre8 when used on ext4 without a journal.
I haven't tried other cases (ext4 with a journal or other file systems)
so I cannot speak for those, but in the mentioned use cases it is
completely repeatable.
