Bug Description
Using Ubuntu 11.10 Beta 2 64 bit -- clean installed on a brand new laptop (dual boot with Windows 7).
When I tried to load ATI/AMD proprietary drivers, the install process stalled at about 2/3 done in the "downloading and installing drive" dialogue window. System monitor shows one CPU at 100%, and the other at about 30%. All systems functions are very slow, especially network I/O. (am using wifi) I cannot tell accurately what process is using the CPU due to lack of an "all process" selection in System Monitor under Unity. Earlier today I experienced a similar problem when running Ubuntu Software Center, so I suspect a common cause.
[Note -- this system had the installation crash with the just-fixed installer bug. It booted anyway, so I kept using it, assuming that software update would catch any serious problems. Perhaps a mistake, but installs worked okay until this morning.]

More information:
I finally located the controls I needed in System Monitor. Of course, under Unity the menus had migrated from the actual application window up to the system's top bar. What a confusing mess! Whoever came up with that grand idea should be flayed with thousands of wet noodles. But I digress...
The actual program which was using 100% CPU was Dropbox, running as root, attempting an update. I have reported that bug to Dropbox.
So this bug report becomes: When some other process is running at 100% root CPU on one processor, software install attempts stall forever even if other processors are available.
