Or other pointers? The freeze could be the kernel panicking. If you're running X at the time, you will most likely not see the panic message or ddb prompt. If you're able to reproduce this consistently, try switching to another console (e.g. alt-ctrl-F1) and starting the vm there. That way if there's a panic you should see it and we can better dig into the issue. > > dmesg, vm.conf, and sysctl.conf attached. > I didn't see anything abnormal in dmesg or vm.conf. I'm not familiar with the sysv_shmem kernel stuff, so no idea if those settings make sense. -dv
