Known issue. Use 3.8.3 and higher with qemu 1.4+. There's a known issue with qemu 1.3 with newer kernels (>3.7).
You'll also need to adjust the boot script to include the DTB, eg:
qemu-system-arm -machine vexpress-a9 -m 1024 -nographic -net nic -net user \ -append "console=ttyAMA0,115200n8 rw root=/dev/mmcblk0p2 rootwait physmap.enabled=0" \ -kernel "$KERN" \ -initrd "$RAMFS" \ -sd "$IMAGE" \ --dtb dtb-3.8.3-102.fc17.armv7hl/vexpress-v2p-ca9.dtb
The F18 Vexpress image includes the DTB option in the boot script already. Should work after that, let us know if you have any further issues.

What's the command line you're using to boot it? Are you specifying a dtb file?

The last known good kernel is 3.7.6-102.fc17.armv7l.What's the command line you're using to boot it? Are you specifying a dtb file?
Peter
The full script I use is below. Every time I test a new kernel, I copy vmlinuz, initrd, and the dtb directory. All of my tests were done with vexpress-v2p-ca9.dtb for each kernel.

Last kernel I could boot correctly under qemu is 3.7.6-102.fc17.armv7l.
When I try 3.7.9-101.fc17.armv7l, I get this under qemu-1.4.0 :
I have now tried 3.8.3-102.fc17.armv7l and it still fails to boot. The last known good kernel is 3.7.6-102.fc17.armv7l.
Hi Alex,
I was able to boot 3.8.3-102.fc17.armv7l and the latest kernel-3.8.5-101.fc17 using qemu-system-arm-1.4.0-9.fc19.x86_64. Using the provided boot script you would only need to add the required 'dtb' to the existing command, for example:
qemu-system-arm -machine vexpress-a9 -m 1024 -nographic -net nic -net user \ -append "console=ttyAMA0,115200n8 rw root=/dev/mmcblk0p2 rootwait physmap.enabled=0" \ -kernel "$KERN" \ -initrd "$RAMFS" \ -sd "$IMAGE" \ --dtb dtb-<kernel version>/vexpress-v2p-ca9.dtb
In 'qemu-system-arm-1.4.0-9.fc19.x86_64' A15 support is also working using those kernels, changing the hardware (-machine vexpress-a15) in boot script and using the vexpress-v2p-ca15_a7.dtb from the kernel package. Using A15 will allow an increase to 2 GB of ram, however there were a few backtraces at the beginning of the boot.
