strange ext2 fs (?) problem: 2.0 kernels not mounting root fs anymore

Hello,

I have no idea at the moment what's going on here:

Yesterday I booted 2.1.96 (with new kmod.c by Mikael Pettersson - and
no "make clean" after the 2.1.95 compile) which gave an kernel oops
in swapper (I think) a bit before mounting the root fs (ext2 on IDE
/dev/hda2) ro. Systems halts/stops when trying to remount the root fs rw.
(I could reproduce that (and have done so), but I'm not too eager to do so.)

Now for the interesting part:
After rebooting 2.1.95 a filesystem check has been required (e2fsck 1.06,
system is not up to date in all parts) but completed without any
corrections. I don't notice any problems with this partition either under
2.1.95.
BUT: If booting 2.0.x kernels (tried 2.0.32, 2.0.30, 2.0.28 images from
that root fs which worked flawlessly before; and also booting a kernel
image from floppy) the system simply stops shortly after
"VFS: Mounted root (ext2 filesystem) readonly." - with 1-2 s disk
activity after that message.

Any ideas?
Lutz
