Public bug reported:

Binary package hint: linux-image


I'm running an up to date (as of today) gutsy with linux-
image-2.6.22-14-generic 2.6.22-14.52

The last two updates, I believe all in Feb, have resulted in a new
behaviour in my system.

I have two ATA drives in this desktop machine, one 20GB that used to be
root, and one 200GB that has replaced it. I've moved root onto the new
drive and have left the old drive in the machine as a backup system in
case the new drive goes.

So the drive is physically in the machine and powered, but is not in
fstab and is never mounted.

It used to spin up on reboot and then eventually go to sleep and turn

Now with these updates after it has been off for 1min, it spins back up
again. So its constantly spinning up and down, whereas before it would
spin up once, spin down and stay spun down.

I can test the behaviour by running this command to spin down the drive:

sudo hdparm -y /dev/hdb

One minute after running this command the drive spins back up, I can't
find anything in the logs that explain any attempt to automount or
anything else that would spin up the drive.

Should I just remove the power from the drive to save its life?

The 20GB drive is also damn loud and I would really like it to shut up.
I'm just doing this for now to save the drive:  while(true) do sudo
hdparm -y /dev/hdb; sleep 60; done

I'm issuing this as a bug, rather than in the forums, because its new
behaviour in the recent updates, and I can't see it as being
