dd if=/target/boot/vmlinux of=/dev/scsi/..../lun0/part1
begins to write on disk then : "dd : of=/dev/...." Input/Output error.
I dumped the very first of .../lun0/part1, there is an ELF header and a lot of
binary following.
and the machine doesn't boot. Because of that error I think.
part1 is 8.2 MB and vmlinux about 4.
parted shows the part as prep boot.

I tried also boot net then load : ....console=tty0 noinitrd, hoping it was
able to find root as /dev/sda3 which exists now but always the same:
cannot open root device "<NULL>...."
if load: ... root=/dev/sda3 we have
cannot open root device "sda3..."
just for fun load= ... root=/dev/scsi/.../part3 all the same
