I just got an MX80 that won't boot 10.4 software.  Like you, I did not
want to upgrade to newer software yet, as my existing MX80s are all
running 10.4R4.5 and we are satisfied with it.

FYI my Midplane is REV 09, PEMs REV 04, QXM REV 06.  All part numbers
are identical to my existing MX80 routers in this network, the only
difference is the hardware revision numbers, and the fact that this
device doesn't seem to want to run 10.4.  I guess I won't plan on
deploying any new MX80s until I have time to test 11.2 or newer.
