Description Peter Jeremy freebsd_committer 2016-07-30 20:48:47 UTC
I'm trying to boot the 11.0-BETA2/amd64fud):

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.
