You vs. ACPI

YONETANI Tomokazu noted that there is a kernel environment variable called ‘debug.acpi.disabled’, to which you can specify the following keywords:

   acad bus button children cmbat cpu ec
   isa lid pci pci_link sysresource thermal timer

“acpi” disables everything
“bus” disables “children”
“pci” disables “pci_link”

Dragonfly song

A band named Universal Hall Pass (which is Melissa Kaplan, formerly of the band Splashdown) has a song called ‘Dragonfly’, two versions of which are available on the band ‘Sound’ page.

This has nothing to do with DragonFly BSD, other than coincidence in name.
