rtorrent downloads broken, possibly related to recent mmap work
Running DragonFly v18.104.22.168.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.
Tim, would you mind updating a box to the head of the master branch and set pmap_mmu_optimize to 1? And then try to reproduce the previous problems? We are hoping it is fixed with this commit: http://gitweb.dragonflybsd.org/dragonfly.git/commit/a44410dd8663abb121417692995d3b365f32fd6e
