I am pissed and lost. I went through something like this when 7.3 came out. Had to use a development kernel for Ext3 support. Well, 2.4.19 has Ext3 built in. I checked it like in 7.3 and build the cursid thing all went well, or so I thought. Went to reboot and "kernel panic" cannot boot. I can only asume for whatever reason it is not using the Ext3 filesystem. Anyone else had this problem? I don't know much about this type of this and I am at a loss for an explnaion.
Far as I know a default Redhat install of 7.3 has ext3 enabled (I have one box running it with out a problem). The only time I had a problem with it was when I built a custom kernel. If I remember right both 2.4.18 and 2.4.19 default configs (from kernel.org) do not have it enabled. It has to be enabled before the build.
