Peter, the pull request this supersedes apparently failed your tests on an arm32 host, so it's very likely this one does as well. I've been unable to reproduce the problem on a handful of arm32 machines I was able to borrow access to, and I'm beginning to suspect the problem is something specific to the library/distro versions on your test machine rather than something inherent to arm32.
I'm afraid I'm going to need help from you to fix this: either debugging on your part, borrowed access or many more details of the error. At this point I simply have nothing whatsoever to go on to debug the problem.

It has been rebased and retested and has one extra patch, but is otherwise unchanged. Here's a second batch of patches for qemu-2.12. Highlights are: * Optional capabilities for the "pseries" machine. This removes some places where we were changing guest visible properties based on host capabilities, which makes life very bad for migration. * SLOF update * Significant TCG speedup from Paolo * Several new devices for embedded platforms * Some minor cleanups ---------------------------------------------------------------- Alexey Kardashevskiy (1): pseries: Update SLOF firmware image to qemu-slof-20171214 BALATON Zoltan (4): sm501: Add panel hardware cursor registers also to read function sm501: Add some more unimplemented registers ppc4xx_i2c: Implement basic I2C functions hw/ide: Emulate SiI3112 SATA controller Cédric Le Goater (2): ppc/pnv: change powernv_ prefix to pnv_ for overall naming consistency target/ppc: more use of the PPC_*() macros David Gibson (6): spapr: Capabilities infrastructure spapr: Treat Hardware Transactional Memory (HTM) as an optional capability spapr: Validate capabilities on migration target/ppc: Clean up probing of VMX, VSX and DFP availability on KVM spapr: Handle VMX/VSX presence as an spapr capability flag spapr: Handle Decimal Floating Point (DFP) as an optional capability Greg Kurz (1): spapr_pci: use warn_report() pbonz...@redhat.com (1): target-ppc: optimize cmp translation MAINTAINERS | 6 + default-configs/ppcemb-softmmu.mak | 1 + hw/display/sm501.c | 30 +++ hw/i2c/ppc4xx_i2c.c | 198 +++++++++++++++++--- hw/ide/Makefile.objs | 1 + hw/ide/sii3112.c | 368 +++++++++++++++++++++++++++++++++++++ hw/ide/trace-events | 5 + hw/ppc/Makefile.objs | 2 +- hw/ppc/pnv.c | 94 +++++----- hw/ppc/pnv_bmc.c | 2 +- hw/ppc/pnv_core.c | 8 +- hw/ppc/pnv_lpc.c | 16 +- hw/ppc/pnv_psi.c | 4 +- hw/ppc/pnv_xscom.c | 10 +- hw/ppc/spapr.c | 47 +++-- hw/ppc/spapr_caps.c | 341 ++++++++++++++++++++++++++++++++++ hw/ppc/spapr_pci.c | 6 +- hw/ppc/spapr_pci_vfio.c | 2 +- include/hw/i2c/ppc4xx_i2c.h | 3 + include/hw/ppc/pnv.h | 10 +- include/hw/ppc/pnv_xscom.h | 4 +- include/hw/ppc/spapr.h | 46 +++++ pc-bios/README | 2 +- pc-bios/slof.bin | Bin 905200 -> 913880 bytes roms/SLOF | 2 +- target/ppc/cpu.h | 56 +++--- target/ppc/int_helper.c | 2 +- target/ppc/kvm.c | 27 +-- target/ppc/kvm_ppc.h | 2 - target/ppc/translate.c | 29 ++- 30 files changed, 1135 insertions(+), 189 deletions(-) create mode 100644 hw/ide/sii3112.c create mode 100644 hw/ppc/spapr_caps.c
