These grub commands work with SUSE 2.4.19-4GB:

   kernel (hd0,0)/bzImage root=/dev/hda3   vga=791
   initrd (hd0,0)/initrd

But with 2.5.50 the kernel panics after Freeing the initrd memory with
"Unable te mount root FS, please correct the root= cammand line"

I have compiled with the required file systems (EXT2,EXT3,REISERFS).

grub that came with RH 8.0 can boot 2.5.50 with no problems.

- what is the filesystem on /dev/hda3 ?
- do you have the FS *compiled into the kernel* ?
- did you rebuild your initrd?

Otherwise your old initrd will have old modules, and the FS module won't
load into your new kernel. If you compile them *into* the 2.5.50 then it
will just complain. That's what I did.

Did you also compile in support for the root device itself (i.e. ide or
scsi driver). These are loaded via the initrd normally on SuSE, which
will not work, if you did not install newer modutils..

First of all, 2.5.10 has sysfs-related bug. try to replace root=/dev/hda3
by root=303
