Description

Running DragonFly v3.3.0.165.gdc43b7-DEVELOPMENT, x86-64

Since upgrading to recent master, rtorrent downloads have been frequently failing with the message "hash check on download completion found bad chunks". I've never that message from rtorrent before. I tried setting machdep.pmap_mmu_optimize=0 and the failures stopped.

Thanks for adding that link, Francois. If this is in fact a bug in rtorrent, I don't have much hope that it will be fixed, given that this bug report is 6 years old.

We cannot completely exclude a DragonFly issue either.

It would be interesting to get both good and bad copies of the same file.
Knowing the corruption pattern may help find a possible root cause.
