Error 6 is ENXIO, which basically means that the device suddenly
disappeared, as far as geom is concerned.

Are you using RAID or a mirror?  ENXIO seems to only be set in
geom/geom_fox.c, geom/mirror/g_mirror.c and geom/raid/g_raid.c.
That is, bio_error, which is what is being reported, is only set
to ENXIO in these files AFAICT.
