Complain to the iscsi people perhaps...?

__end_that_request_first() in block/block-core.c() is what is issuing
your first error,

and the rest is xfs reacting to that.

Maybe the first thing I'd check is whether that sector nr. is sane for
your device (I'd assume it is, but maybe worth checking).

If that's all you've got I'm not sure offhand what else to debug....
