Starting a VM, Windows XP or Ubuntu x86, with a VM Network Adapter attached to NAT, after few seconds the laptop freezes. The system responds only to power off, pressing the power button for few seconds. The only things I can do is a photo of the screen: https://plus.google.com/112995826906094353410/posts/6amoaitgP8e It works if the VM Network Adapter is attached to Bridged Adapter.

I am experiencing this issue too, using r275563. I mailed current@ about this and a first analysis of the data by kib shows it's not a ports problem but most probably a base problem in the network stack: https://lists.freebsd.org/pipermail/freebsd-current/2014-December/053663.html
I investigated the issue. By bisecting the source I discovered that the issue appears with r274712. In fact reverting the change in that commit in recent head (I'm running r275730 with r274712 reverted) makes the problem disappear. Hope this helps in understanding the problem and find a fix.
Thanks Guido, it works for me too. I'm running r275515 with r274712 reverted.
I expect r275955 to fix the problem. Can you check that please?
Thanks Gleb it works. I am running r275958, checked with these VMs: Windows XP, Ubuntu MATE x86 and GhostBSD x64.
