bio is no longer contiguous with the previous bio;

We encountered frequent boot failures while setting up a dm-verity rootfs with
the following configuration, and found that this issue had been reported
previously:
root=/dev/dm-0
dm-mod.waitfor=/dev/mmcblk0p23
The error observed was:
device-mapper: table: 254:0: verity: Data device lookup

I ran into an issue where multipathd wasn't tracking a multipath
device that was created by the multipath command. It turns out that if
multipathd fully initialized a path device, and that device later
goes offline and then a multipath device that could use that path is
created by multipath, multip
If a multipath device was created by the multipath command, multipathd
might not agree with how the device was created. ev_add_map() can reload
the device with a different table by calling add_map_without_path() ->
update_map(). If this reloading of the map failed, multipathd was simply
ignoring th
