Hi Trevor, and sorry for the delay. I have read all the replies (which
all focus on the DMA issue) but I have another theory.
Are you sure it's Nautilus that hugs all the CPU while copying? When
the problem happens again, run “System Monitor” and see what really use
the CPU (in my theory it's “gam_server”). That's normal (in that it's
not specific to you) and it *should* be fixed in Breezy.
What really happens (in a nutshell) is that “gam_server” monitors the
directories that have an *open* Nautilus window(s) plus other important
ones (like the Home, Desktop, /use/share/applications, /etc/xdg/menus,
and more others). To see what “gam_server” monitors, run:
lsof -n | grep '^gam_serve.*DIR'
