After looking for more information, I found this comment on a forum.
====================
Hi,
this must be a new bug with Linux kernel or udev.
A significant difference between CD TAO and CD SAO at read time
is that a TAO track ends by two non-data sectors, which cannot
be read by normal SCSI READ commands.
This can happen only with CD media. Not with DVD or USB sticks.
In the times of kernel 2.X, the situation in the Linux kernel was
quite bad: I/O error somewhere beginning 128 blocks before the
track end.
With kernel 3.X it improved. The I/O error reliably hits 2 blocks
before track end on 3.16. I did not try 4.X with real iron yet.
My best guess would be that this confuses the entity among the
ISO payload, which is in charge for creating /dev/disk/by-label/ 
links while the system boots up.
(If somebody can explain the factor 8 between "sector 1226752"
and "logical block 153344", then please do.)
Obviously the problem is still in archlinux-2016.02.01-dual.iso

After testing his theory and burning the ISO to a DVD instead of a CD, it
worked!

Does this shed any light to the problem?
