2.2.21 kernel with initrd not loading intermittently

I have a problem that I have been wrestling with now for a number of days
with no solution, and I'm hoping someone can help.

I have a stock 2.2.20 kernel with ramdisk and initrd support compiled in.
RAMdisk size is 64MB although I've also tried 32MB and 128MB.
I have tried kernel builds with module support and without (everything
compiled in)
I'm using the latest lilo I can find with the following config:


The server is a uni processor PIII server with 512MB of RAM

The sizes of my rootfs.img and kernel are:
 8713856 Aug 7 12:55 rootfs.img (this is an ext2 compressed image)
 787022 Aug 7 12:17 vmlinuz-2.2.20up (this is a monolithic bzImage kernel)

My problem is that when my kernel loads, sometimes lilo doesn't seem to load
the rootfs.img into RAM for the kernel to find. That is I don't get the
kernel message 'RAMDISK found at 0' message and thus Linux panics with
something like "root file system not found on dev 1:0".

Lilo when building doesn't report any errors in fact it says it successfully
maps the RAMdisk ok

The only trick that I have been able to use to get around it, is to
selectively remove some files OR selectively remove some kernel components
when compiling - but it's not consistent. It almost seems like there is some
finite size limit that my rootfs.img+kernel is greater than that stops the
RAMdisk being loaded or being found if it is infact being loaded.

I have not tried a 2.4 level kernel as I need this to work consistently with

Any help much appreciated.
