Improper disk shutdown with 2.6.22.6?

Improper disk shutdown with 2.6.22.6?

[Robert]

Hello,

When shutting down this system running Linux 2.6.22.6, I get a warning about
the possibility that the disks are not properly shut down. When the power is
turned off, it sounds like the disks aren't spun down (but I may be mistaken
on that point).

http://linux-ata.org/shutdown.html claims that kernels newer than 2.6.21 will
always spin down the disks, but is this really the case?
The manage_start_stop files exist.

Tell me if you'd like more detailed information about configuration and
hardware.

You're on debian, right?  You need to update your shutdown utilities.

Henrique, what information should we put into the faq page to properly
direct debian users to needed updates?

Thanks.

Thanks for your help.

I'm on Debian, yes, and now I applied the change to /etc/init.d/halt in
http://lists.alioth.debian.org/pipermail/pkg-sysvinit-commits/2007-June.txt
and I'm using HDDOWN=NEVER in /etc/default/halt, which seems to work.
