When booting on a 4k NVMe disk, the kernel will always print:
hib block_io biowait error 22 blk 4229561 size 512
This is from hibernate_resume() trying to read the signature of a
previous hibernation. ZZZ also fails in the io path.
A bunch of things in subr_hibernate.c have DEV_BSIZE (512)
hard-coded, which goes through hibernate_block_io(), and then
bounds_check_with_label() in subr_disk.c which returns EINVAL
because the block number is not divisible by 8 and the block count
(512) is not divisible by d_secsize (4096).
