Sorry for the delay in getting back to you on this -- I've been on travel, and don't often check the smp@ mailing list for posts. You may want to take this to the stable@ mailing list, which is frequented by quite a few people willing to lend a hand debugging. It sounds like there there are a lot of variables in flight here. Would it be possible for you to see if you can reproduce the problem with just one of netatalk and samba in use? Also, could you try upgrading to the latest 6-STABLE, and compiling your kernel with INVARIANTS, WITNESS, KDB, and DDB? There's a section in the developer's handbook on setting up for debugging. With these debugging tools in place, it will be a lot easier to track down this problem. Finally, if we do end up doing much kernel debugging, you will want to use a serial console so that you can copy/paste the debug output on a second machine rather than copying it by hand (firewire console also works for this).
