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.

Please be more specific of your configuration, including full 'gpart show' output, list of mounted file systems, uname -K output, exact text of commands and system responces.

Then one for this issue when cleaned up. And probably another for the geom.debugflags footshooting semantics. Also I need to capture that mount -uw panic but have to look up again the sysctl to prevent instant reboot / leave it onscreen or to debugger.
