Apologies, I wasn't using sid, and that line wasn't in the previous
version. Now that I've upgraded my acpi-support package, it works fine.
One more thing though: To avoid these messages (since my virtual SCSI
drive and my USB drive don't support hdparm -i) ...
# /etc/acpi/start.d/90-hdparm.sh
HDIO_GET_IDENTITY failed: Invalid argument
HDIO_GET_IDENTITY failed: Invalid argument
... I'd suggest you apply the attached patch, which discards errors.
Then everything works fine!
BTW, why are you running the acpi-support package on a VM?
It's basically a left-over from my previous system, when I copied it
over to my VM. I believe I'm now only using acpi-support to get visual
feedback when I plug in or unplug the AC adapter. :-) (It also used to
spit out low-battery warnings until I stumbled upon an OS X widget that
runs on the host and does it in a prettier way.)
Best,
