The section of the dmesg and the location where the boot freezes.

ohci0: <SiS 5571 USB controller> mem 0xcffce000-0xcffcefff irq 10 at 
device 2.2 on pci0
usb0: OHCI version 1.0, legacy support
usb0: <SiS 5571 USB controller> on ohci0
usb0: USB revision 1.0
uhub0: SiS OHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 3 ports with 3 removable, self powered

The boot hangs at this point. It also freezes the kvm switch. It was 
cvsup'ed at 1822 PDT ( 0122 UTC). I am back to running the kernel from 
30 August.
