To reproduce this issue just do the following: % wget http://torrents.linuxmint.com/torrents/linuxmint-12-gnome-cd-nocodecs-64bit.iso.torrent % rtorrent linuxmint-12-gnome-cd-nocodecs-64bit.iso.torrent (Wait until the torrent finishes) % sudo echo 3 > /proc/sys/vm/drop_caches (Rehash the torrent (Ctrl-R)) The torrent doesn't rehash successfully and a few hunks are missing/corrupted and need to be downloaded again. -- Markus -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
