Comment 2 for bug 200154

Hardy Kubuntu up to date as of yesterday (19/3/08)
I did same . . .

I was running amarok too. But not an iPod, a usk disk was plugged in

Amarok ran to the end of the current song then stopped, which made me notice a problem. No system response at all X wise, I had to Alt-F1.
I tried my user account & password, no login possible (hung where normally prompt appears). So i used root, which logged ok.
ran top and 95.5% cpu was kded.... killall -9 kded brought everything back immediately.

heres my dmesg :
