The first two big ones are: - Doesn't like gdb 6.0 (You cannot assume the first packet is Hc...) - Wierdities with kgdb_killed_or_detached / kgdb_might_be_resumed (both can die). - All of the function pointer games (of which the weak symbols, but not all of them) are a part of. - Issues w/ handling 'D' and 'k' packets cleaner (and I think there was a correctness fix in there, too, but it was a while ago). - Don't ACK packets sitting on the line - kgdb_schedule/process_breakpoint, required for kgdboe, harmless to use on serial.
There's still a lot of stuff I checked into linux-2.6-kgdb that's non-trivially important (http://ppc.bkbits.net:8080/linux-2.6-kgdb/ChangeSet@-4w?nav=index.html)
