Subject: torrent hash failures since 3.9.0-rc1

I get hash failures on "completed" torrents since 3.9.0-rc1 (Linux 3.8
seems to be fine). What happens is that the torrents apparently complete
successfully. After reboot however the hash check fails and there are
missing (or corrupted) chunks. I've tested this with two different
clients (rtorrent and aria2c) and both are affected. So I think this
might be a filesystem issue.

/dev/sda       ext4      1.4T  666G  640G  51% /var
/dev/sda on /var type ext4 (rw,noatime,data=ordered)

I use ECC memory (and there is nothing in the logs).
