Your disk > layout sucks, and you need to shrink/move your root filesystem. Specifically, since it obviously worked before, I'd guess that your root file system is very large, but starts before the 1024 cylinder limit. The kernel normally gets installed at the beginning of the file system, but since you installed a debug kernel, there was not enough space there, and parts of it ended up (way) beyond the 1024 cylinder limit. You might find that if you strip the kernel, you can still boot. You can still keep a copy of the kernel with symbols for remote gdb debugging, if that's what you want to do.
