When plugging an iPhone to a Ubuntu 10.04 machine for a few times, the CPU becomes busy with 100% utilization.
This is due to some bugs which causes both iphone-set-info and gvfs-afc-volume-monitor processes to fully utilize the CPU.
The problem can be fixed by stopping both processes from the terminal.
$ sudo killall -9 iphone-set-info password:
$ sudo killall -9 gvfs-afc-volume-monitor
