It reached 70% and then wrapped back to 0%. Why does it happen? A bug? There seems to be a problem with booting up 4.8-RC on a 4GB machine. The kernel reaching multiuser mode produces message about unability of allocating new u_map and panics. This is HyperThreading enabled machine (2+2logical CPUs). Any ideas?
