Bug Description
Trying to run 9.04 live CD and every time I adjust the volume with the knob on the side of my laptop, the notify-osd process goes to 100% of cpu and stays there making X effectively lock up. The mouse cursor is still visible and moves, but nothing else works. When I switch to a console, and run top, I see notify-osd at 100%. If I kill the process, notify-osd just comes back and resumes using 100% of CPU.
I'm on an Toshiba Satellite laptop. Model U-305-s7449.
This is very reproducible and happens within seconds of touching the volume knob (which works fine in 8.04).
I'll play around with this more later. I'm not exactly a newbie, but I'm not a programmer either so some hints to diagnose this would be welcome.

A little more about this bug. I've been playing around with this some more and the notify-osd process seems to behave just fine until I touch the volume knob on the side of the laptop. I can adjust the volume using the mouse and the volume icon at the top of the screen with no problems.
Also I can trigger notifications for other reasons (like connect and disconnect from wifi) and notify-osd wakes for a second or two, shows the notification, then goes back to "sleep".
However, if I even touch the volume knob, the volume notification pops up and runs away to maximum or minimum volume and begins to consume 100% CPU. Killing the process doesn't do any good, because it just restarts.
As long as I don't touch the volume knob, everything is fine. In fact, I'm typing this now from the Live CD. I'm afraid to install 9.04 to replace 8.04 because I don't want to have a runaway volume notification every time I touch the volume.
Is there anything else that would be helpful to diagnose this? lspci printout or something similar?
Let me know and I'll post whatever.
