For similar occasions I wrote a ggatel patch as a workaround: https://www.fabiankeil.de/sourcecode/electrobsd/ggatel-Optionally-retry-req= uests.diff Later on I stumbled over gmountver which you may want to try first. At least on my system it doesn't work unless I disable kern.geom.mountver.check_ident (which obviously is dangerous), but I didn't have time to investigate this yet. > Dmesg shows that the device is removed from the devfs with a=20 > passdevgonecb/lost device message.
