I'm wondering what debug sysctls to use to see what's going > wrong. I was copying from a fat32 partition to an ext2fs partition on the same USB drive, so this fits.

It successfully passed a make -j2 buildworld/buildkernel with src and obj on the same partition, and a ports build of libreoffice (and its several dozen deps) with ports and WRKDIRPREFIX on the same partition, part of which overlapped with the world build.
