Apologies if this sounds like a "Me Too" but, I'm experiencing a freeze 
at the exact same point -- My Microsoft 5 button optical mouse is probably
a different revision.  Also probably a different USB controller.

I have not tested any of the work-arounds (removing the USB device), but
Mine is a SIS chipset board.  (ECS K75SA)   Unfortunately, I'm away from
the affected hardware until next weekend.

Previous (working kernel) is from about 8/22 ...   non-working kernel
is from 9/20.
