FreeBSD 11.0-BETA2 won't boot on an Acer Aspire 5560

[Peter Jeremy]

I'm trying to boot the 11.0-BETA2/amd64 memory stick image and the
kernel panics: (Following copied by hand):

ACPI APIC Table: <ACRSYS ACRPRDCT>
...
acpi0: <ACRSYS ACRPRDCT> on motherboard
ACPI Error: Hardware did not change modes (20160527/hwacpi-160)
ACPI Error: Could not transition to APCI mode (20160527/evxfevnt-105)
ACPI Warning: AcpiEnable failed (20160527/utxfinit-184)
acpi0: Could not enable ACPI: AE_NO_HARDWARE_RESPONSE
device_attach: acpi0 attach returned 6

Followed by a NULL dereference panic at nexus_acpi_attach+0x89

The system boots a 10.0-RELEASE/amd64 memstick (the only other image I
have conveniently to date) without problem.
