You might want to try setting ramdisk_size too.  It's been a while since I
played with this stuff and the argument may be called something else.

I definitely do

What other informatin would be useful?  This has got me stumped.  The
ramdisk support in the kernel seems to be working OK.  I booted the
system up with an nfs mounted root partition and did the following:

        #dd if=/dev/zero of=/dev/ram0 bs=1k count=4096
        #dd if=/fs of=/dev/ram0    (fs is my filesystem image)

This went off without a hitch so I tried mounting /dev/ram0:

        #mount /dev/ram0 /mnt

also fine and when I look in /mnt the filesystem looks OK too.
