Why are you mounting the ramdisk on your /dev/ directory?? This might in itself cause problems. Linux doesn't seem to mind too much using a directory with files in it as a mount point, however I have always understood that Unix tends to like an empty directory.
Using devices on a ramdisk works very well (to 2.0.29 anyway), I use them every day. One problem I found is that sometimes mke2fs messes up when creating the filesystem. I didn't quite follow up on this, I'm not sure if it not a hardware problem. Specify the number of blocks to mke2fs, eg:
mke2fs /dev/ram 32
