While we are at that, ghost (or non-active) paths lead to _tons_ of
errors while the kernel stubbornly tries to read the partition table,
totally flooding any useful information out of the kernel buffers.
Can't we do a test-unit-ready before trying to read and then just not
read the partition table w/o so much noise?
