At this point, the host CPU just spins. The previous kernel from saucy (3.11.0-19-generic) boots correctly into the trusty environment.
The VM is being launched as so:
export QEMU_AUDIO_DRV=none
exec qemu-system-arm -display none -M vexpress-a9 -kernel /srv/arm-dev/u-boot -m 1024 \
-serial stdio -net nic,model=lan9118,macaddr=52:54:00:68:90:14 \

-pflash /srv/arm-dev/pflash1.img -pflash /srv/arm-dev/pflash2.img -smp 1
The flash images are unused; the scr points to the SD:

== SRU Justification ==
Upon d-r-u of a qemu ARM guest from saucy to trusty, the kernel no longer boots:
== Fix ==
Build the correct dtb for this board and disable the console-over-jtag
or
Apply the attached patches, recompile and install.
== Impact ==
Kernel hangs at boot.
== Test Case ==
Try booting your installation with and without those fixes.
