I am having this problem too on an x86 machine with ext3 filesystem.
rtorrent stops downloading and says:
Hash check on download completion found bad chunks, consider using
"safe_sync"
This is the case whether safe_sync is used or not. Download resumes if I
start the torrent again manually. This could happen multiple times, but
once the download is complete hash check succeeds.
I am running a debian kernel 2.6.18-3-686, debian testing (etch).
