I didn't notice any recent commits that seem relevant and assume the issue can occur on other branches as well. For now I'm using the attached patch to let g_dev_orphan() return early if the device is already gone. A more elegant solution could be to prevent geom from trying to orphan the device when it's already gone but I haven't looked into this yet. --=20 You are receiving this mail because: You are the assignee for the bug.=
