[ELDK] Native compiling freezes with swap over nfs!

OK. I just wanted to be sure, but this certainly sounds as if your
hardware was running OK.

Yes. You are certain that your hardware works, and that the NFS server
works - otherwise you should have seen issues with the other builds as
well.

Now all the rest - task and memory management, swapping, network - is
part of your kernel. If this is broken, it is almost certainly a bug
in the kernel code.

Note that this may be not a new bug; there is very few people who test
such a configuration, and issues may go undetected for a long time.

Best regards,
