This is still an issue for me, albeit not as bad as the original reporter
claims.
With hald-addon-storage active, powertop shows that ata_piix causes about 10
wakeups / s.
This is totally eliminated when hald-addon-storage is killed.

Per Hoffmann's last comment I'm marking this Fix Released for Intrepid.
Stefan Fleiter, since you are the original bug reporter, if this is not
the case please feel free to reopen this report by setting the status

Installing linux-image-2.6.27-* onto a Hardy setup solves this problem

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:

wasn't asynchronous notification supposed to be merged into the
2.6.24-rc2 kernel?
if so, why do we still need to rely on hal drive polling for insert
notification?

Seems to me that at least when on battery power there ought to be a way
to reduce the polling frequency considerably. Surely once per second
should be enough for a CD?

There's no way to probe most CD drives without generating interrupts, so
there's nothing hal can do about this.

Matthew:
That's right. This bug report is not created because wakeups occur, but because
there
are 50 wakeups/second per cd drive.
The strace output of halld-addon-storage seemed reasonable to me,
so I added the kernel here which I do not know how to trace in detail.

Looking at the strace log this looks more like a kernel bug now.

I've straced hald-addon-storage.
The output seems reasonable.

I do not see that much wakeup events
cdrom should be polled once/twice a second
however powertop suggests to disable polling of /dev/scd0
