I will have to build DDB into my kernel and see what I can find out about where it's stuck. I also intend to remove the SAS controllers and disable USB and various things I can do to see if it stops being 100% reproducible on this particular system. I just patched in the following as a MFC and this also did not affect this issue: http://svnweb.freebsd.org/base/head/sys/geom/geom_disk.c?r1=240629&r2=241022&view=patch That is 240822 and 241022 combined: http://svnweb.freebsd.org/base/head/sys/geom/geom_disk.c?r1=240629&view=log
