Is the symptom that when u-boot tries to find the drive, it stops with a
"T" and won't go further?  I see this on one of my sheevaplugs and afaict
it's because the drive spun down.  This is why I have a "reset" at the end
of the boot command -- if the timeout happens, the plug reboots, the drive
is still spinning and the boot works.
This happens every time I complete a reinstallation of the plug (I assume
because the spin down delay is just short enough that by the time the
installer has shut itself down, and the system's rebooted, the drive has
spun down).
