I can reproduce a hang in the md driver reliably. Setup: dd if=/dev/zero of=image bs=32k count=8k vnconfig -s labels -c vn0 image diskabel -r -w vn0 auto newfs vn0c dd if=image of=/dev/md0 bs=32k count=8k mount /dev/md0c /mnt This works as expected. If I run bonnie against /mnt with a 64M filesize, everything is fine. However, once I up that size to 128M it will hang half way through. Using an mfs partition instead yields no problems. I've tested this against a 4.3 (512M ram) and a 4.4 (1.5GB ram) boxes respectively and both are affected. top says the bonnie process is in the "MD sec" state.
