Doesn't reproduce here with this command line (upstream + the bridge patch).
[ 0.568000] PCI: Enabling device 0000:00:12.0 (0000 -> 0002)
[ 0.572000] cirrusfb 0000:00:12.0: Cirrus Logic chipset on PCI bus,
RAM (4096 kB) at 0x10000000
...
[ 1.172000] PCI: Enabling device 0000:00:0a.1 (0000 -> 0001)
[ 1.188000] scsi0 : ata_piix
(with console=ttyS0)
What's lp - p when the segfault occurs? What's *index?

We're setting 16 pages around address 269090816. Should be totally

If you make memory_region_transaction_begin()/_commit() no-ops, we can
get a clearer stack trace.
