Title:
  Cannot boot 3.13.0-23-generic from u-boot on qemu-system-arm

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  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
  setenv bootargs console=ttyAMA0,38400 root=/dev/mmcblk0p2 nosmp
  setenv fdt_high 0xffffffff
  setenv initrd_high 0xffffffff
  bootz 0x60008000 0x61008000:0x1000000 0x62008000
