Mr. Malone, who was handling the PR, has fixed it. (It had to do with MTRR on some of the ASUS boards) The quick and dirty hack still involves recompiling the kernel. First, you'd edit your /usr/src/sys/i386/i386/i686_mem.c file (I'd back it up first, of course, but..) Around line 269 you'll see u_int cr4save; mrd = sc->mr_desc; In between those two lines, simply insert return; Then recompile the kernel. Say you haven't yet made a custom kernel and are using GENERIC. cd /usr/src/sys/i386/conf config GENERIC You'll see source is ../../compile/GENERIC Don't forget to do make depend Then, cd ../../compile/GENERIC make depend && make && make install Reboot and you should be good to go. (You probably know most of this, but if not, this saves you a bit of reading) Then things should work. The whole thing of the spontaneous reboot and nothing in the logs was pretty typical of the problem.
