Upon d-r-u of a qemu ARM guest from saucy to trusty, the kernel no longer boots:

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 \
    -net tap,ifname=arm-dev,script=no,downscript=no -sd /dev/mapper/host-arm_dev \
    -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:

fatload mmc 0:1 0x60008000 vmlinuz
fatload mmc 0:1 0x61008000 initrd.img
fatload mmc 0:1 0x62008000 board.dtb
