Yes, it's pretty much as weird as it sounds. All new machine, forklifted the image from on old i386 machine running 8.x to current on amd64. Everything seemingly works fine, attaching geli volumes shortly after boot is fine, attached devices continue to work fine. There are no strange crashes with this machine or anything, but when I try to attach an USB volume the next day, geli attach segfaults. This seems unrelated to USB however, as the same happens for md(4) devices. % geli status Name Status Components gpt/swap.eli ACTIVE gpt/swap ada1.eli ACTIVE ada1 These all work fine, so I've rebuild geli with debugging symbols and when you run geli init md1: root@coyote:/usr/src/sbin/geom/class/eli# gdb geli GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
