I also had this issue with Openbox-ubuntu-core2duo-ich9/ahci-sata, although it was intermittent, sometimes it would barely work (painfully slowly) clear into the part where I was looking for a distro to copy. I dont mean just "painfully slowly," I mean, "glad I had something else to do," hours and hours. Since then I quit ubuntu for gentoo(<3) and quit openbox for qemu, so I have no related issue- or logs to share, just posting because I had a similiar issue in Openbox.

Anyhow, aloha
