Ok,
Thanks to those of you who helped I've got a patch here which initializes
USB devices earlier in the booting process (e.g. as soon as the hub they are
on is done with hub_configure). It works great for me, loading / over NFS
with a Linksys NIC, and may also help anybody booting off a USB hard
disk/zip drive/etc.
BTW! This patch is against -pre5. It should be fairly obvious, though.
If there's a "Better" way to do this, please let me know. Till then, it
works for me!
Thanks,
Ben
