I am also having issues with my Slate 7 when trying to install the kmod-nfnetlink-queue package it causes the device to reboot and then get stuck at 100% loading screen and won't move forward even after several hours. The device doesn't respond to 192.168.8.1 and it only seems to work after a full factory reset.
