You need iscsid to log in, log out, and for error handling (like if you 
pull a cable or reboot a target).

You can actually kill iscsid after you have logged in, and you can still 
run IO like mount a FS or do run some DB. iscsid is not used for any of 
those operations. However, if there was a network problem we would not 
be able to relogin and recover from the problem until you restarted 
iscsid (if iscsid was on the disk you need to recover then you are 
screwed). And if you want to logout of the target, then you would need 
to restart iscsid, before logging out.

Do you get the access error when trying to log in from the initramfs, 
then do you restart iscsid from there too or do you restart it from 
somwhere else?

The iscsi initiator does not do the scanning. It asks the scsi layer to. 
The scsi layer (this where the message about being too short is from) 
handle this, so it might be due to a change in upstream kernel.

Or, the initiator could be completely screwed up and could be messing up

It is right now.
