I've also seen another error when trying to migrate the process:

$ migrate 1 395359 
migrate: process 395359 has exited/is exiting
$ dmesg | tail -1
add_thread_group:Cannot move process 394990 (gdm) has different tgid 394990
(expected 395359)

It seems confused about which threads belong to which processes.

I get the same behaviours with a 2.6.11 kernel based on CVS as of 16 March.
