I have it running with various 2.2 and 2.3, with only minor hacking. You may also need to increase the rather small symbol table limit in scripts/genkdbsyms.awk (I was a bit surprised too that I run bigger kernels than SGI ;);)
The main advantage of kdb over the usual kgdb stubs is that it is fully SMP aware, can switch between CPUs etc. Now I only need a gdb remote-kdb.c that speaks kdb commands...
