Subjectramdisk problem 2.1.2[56]
When I attempt to build an ext2 filesystem on a ramdisk, mke2fs complains
about not being able erase block 0.  I am able to mount the file system
but any file write operation on the mounted file system hangs.  Is this a
known problem?  I am fairly sure that all of my pertinent libs etc. are at
the correct levels.  I see the same problem with 2.1.25 also.
