The previous kernel was 2.4.12 based, with a hack from me to limit
lowmem to 512MB. And I was using SCSI, which has hardware bugs on my
board, in addition to exercising bounce buffers much more strongly.
In summary, I don't have the faintest idea what was causing the
hangs. I'll try booting my old 2.4.12 kernel NFS root and see if it's
just as stable.
