I have experienced some hard locks similar to what you describe: if I compile usb-uhci as a module, Phoebe3 (8.0.94) locks hard at the time of doing a "modprobe usb-controller" (being usb-controller an alias for uhci-hcd) during boot (rc.sysinit script). To fix this, I have had to compile usb-uhci in to the kernel and then fix rc.sysinit. I haven't tried using usb-uhci as a module since then. What's curious is that doing a "modprobe usb-controller" by hand doesn't cause hard locks. So, there must be some kind of timing or interaction that's causing rc.sysinit to invoke "modprobe uchi-hcd" and freeze the machine. Any ideas?
