I'm trying to compile a small, bare kernel, but it seems I've screwed something up along the way and the kernel goes kablooie...
No filesystem could mount root, tried:
Kernel panic - not syncing: VFS: Unable to mount root on unknown-block (8, 1)
Some additional info:
EXT3 Support: Compiled in
I think the key part might be the empty section after "tried:", since EXT3 is compiled in and it should have at least tried that filesystem.
