Subject2.6.0-test3 _still_ cannot mount root fs
Date
Redhat's 2.4.20 will boot with root=/dev/hda3 pointing to an ext3
filesystem, without an initrd, with the following message

ext2fs warning (device IDE0(3,3) ) ext2_read_super: mounting ext3
filesystem as ext2
VFS: mounted root (ext2 filesystem) readonly

So I assumed that 2.6.0-test3 will also work with ext3 compiled as a module.
I tried the various suggestions root=/dev/hda3, root=0303, root=03:03
without any luck.

I then tested a suggestion that ext3 should get compiled in but get the same
results

Herbert's debug patch produced the same messages with ext3 compiled in.

Any suggestions for what to try next?
