I have a qemu guest for experimenting with -current, 1 CPU & 64MiB RAM. I gave it an NFS swap space to cope with a few small builds, and it now locks up hard after touching that swap device.

Running with the NFS swap space disabled, using a normal swap partition, is fine. This is 9.99.56 amd64, btw. Ideas?
