	I was having the same problem too. It seems that I'd added a printf()
to the target machine's kernel, which would always cause it to drop
whatever the other side was sending. I have no idea why. But I changed
the target's kernel such that it never printed anything between incoming
commands, and then everything worked fine.

	I don't know if this is your problem, but the description is very
similar. It would always get one command through, then drop the next
command and wait for the gdb-host to reissue the command, which would go
through and then the next command would be dropped, etc. This happened
even at low speeds such as 300 baud.
