>Description:
During installation of NetBSD-8 on Sun Ultra 10, Sun keyboard functioned correctly in sysinstall. However when the installed system was booted, Sun keyboard was not responding and nothing was output on the screen when keys were pressed, same issue persisted when running Xorg. When second USB keyboard was plugged in, it functioned correctly, however Sun keyboard was still unresponsive.

By trial and error I discovered that commenting out "ttyflags -a" from /etc/rc.d/ttys resolved the issue and allowed me to use Sun keyboard. Looks like there is a regression with NetBSD-8.
