Sounds reasonable, even though I don't like the way all the sleeps are
implemented. For me they rather smell like workarounds, and not like
real fixes. I guess that the underlying problem is to be found somewhere

So did you just setup your new system with rootfs on an usb device, or
did you suffer from this bug all the time? I'm asking because as I
already reported, newest kernel upgrades obviously introduced longer
delay before usb/firewire devices appear in boot process.
Can you give your exact kernel version, and if it is (built from)
2.6.24-4, would you mind trying an older version to verify that the bug
is not related to some specific kernel version?
