FreeBSD was upgraded from working previously 7.2 with ACPI. Disabling ACPI during the boot helps, and later I was able to isolate the problem to "ec" sub-device (debug.acpi.disabled="ec") >How-To-Repeat: Boot with FreeBSD 8.0 CD with ACPI enabled on Dell Inspiron 1501. Don't have another one to verify though. >Fix: Put into /boot/loader.conf: debug.acpi.disabled="ec" >Release-Note: >Audit-Trail: >Unformatted:
