System hanging in acpi during shutdown

This morning, I upgraded my main system to an up-to-date -STABLE
including acpi and it now hangs during shutdown after reporting:
Waiting (max 60 seconds) for system process `vnlru' to stop...stopped

If I set hw.acpi.disable_on_poweroff=0 then the shutdown completes but
poweroff fails with (hand copied):
ACPI-1287: ***Error: Method execution failed [\_PTS] (Node 0xc21ed450), AE_AML_REGION_LIMIT
AcpiEnterSleepStatePrep failed - AE_AML_REGION_LIMIT

Does anyone have any suggestions other than either removing acpi?

Forcing a crashdump during the hang gives me:

Frame #15 suggests that the code is in AcpiOsWritePort() when I
entered the debugger and this agrees with the results from playing
around in DDB during another shutdown attempt (which reported that
the code was blocked in bus_space_write_1() - which is an 'outb'.

This is a Gigabyte GA-7VRXP motherboard and dmesg reports:
