See the other emails, I was basically just loading random modules. In my case cfg80211, mac80211, mac80211-hwsim - those are definitely available without any (virtio) hardware requirements, so you could use them. Note that doing a bunch of vmalloc would likely result in similar issues, since the module and vmalloc space is the same on UML. johannes
