You should upgrade. Was there a ticket and revision number to look into that? Because this issue is still present in 11.1 and r324300. When booting either from usb... - Mounting ada0s1a read-only on /mnt, and giving the same dd, still produces "Device not configured" upon an ls -R /mnt. A umount clears that condition. Repeat. - After triggering it read-only, but not unmounting to clear it, a mount -uw panics the box. - Giving the dd in unmounted state appears to be ok. Another issue: debugflags=16, manpage say 'allow[s]...write[ing]...sectors... to mounted [read-write?] disk [the aforesaid mounted partition on it?]". The manpage is unclear there. Also geom(8) does not display that actual rank status info, ie: "Rank 1 provider". IMO, 16 should "allow [all] foot shooting". So mode 16 appears to be broken because the dd is denied, even though the dd is NOT writing to the read-write mounted s1a partition itself (which should be allowed even if it were), but is seeking over past it.
