>Description:
When using this CD, ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-8.0/amd64/installation/cdrom/boot.iso
and the shell in the utility menu, the mouse keeps reattaching itself.  Messages get displayed repeatedly in the console like this:

wsmouse0: detached
ums0: detached
uhidev0: detached
uhidev0: at uhub1 port 2 (addr 2) disconnected
uhidev0 at uhub1 port 2 configuration 1 interface 0
uhidev0: Genius (0x458) USB Optical Mouse (0xec), rev 1.10/1.00, addr 2, iclass 3/1
ums0 at uhidev0: 3 buttons and Z dir
wsmouse0 at ums0 mux 0

It seems to happen every minute or so, and but doesn't seem fixed periodic.  This happens to me on a couple different machines.  There is a dmesg from one that had the problem at http://gnats.netbsd.org/53492

The machines currently available to me aren't mine so I can't test any installs on them.

Also, the boot loader and kernel wasn't detecting more the 4G of memory on the 2 different machines I tried that had 8G.   I wasn't sure if that's intentional.  Let me know if a separate PR would be useful for that.

Thanks
>How-To-Repeat:
boot amd64 8.0 boot.iso CD, got to Utility Menu -> /bin/sh
