Thanks for opening the bug Paul. I started a scratch build with the BBB patches removed. Testing that would be step one I guess. http://koji.fedoraproject.org/koji/taskinfo?taskID=5931688 The only other change that looks relevant is the disabling of CONFIG_PCIEPORTBUS to fix the tegra issues. So if the scratch build above doesn't work, we can go there next I suppose. kernel-3.11.0-300.fc20 now boots without issue in qemu-system-arm. There was an update to a number of packages including qemu(qemu-system-arm-1.4.2-9.fc19). Closing this bug. I noticed there was this fix on qemu, not sure if it was related

ARM: PCI: versatile: Fix PCI I/O
The versatile PCI controller code was confused between the
PCI I/O window (at 0x43000000) and the first PCI memory
window (at 0x44000000). Pass the correct base address to
pci_remap_io() so that PCI I/O accesses work.
Since the first PCI memory window isn't used at all (it's
an odd size), rename the associated variables and labels
so that it's clear that it isn't related to the I/O window.
This has been tested and confirmed to fix PCI I/O accesses
both on physical PB926+PCI backplane hardware and on QEMU.
