I have my system hooked up to an iogear kvm switch for display, keyboard and mouse. Sometimes during boot and sometimes when I plug in a USB thumb drive the keyboard and mouse stop responding. Even some of the messages from system init won't show up.
If I disconnect the usb cable from the machine anything I typed while frozen will appear and so will those missing init messages. Plugging the cable back in freezes everything. Scroll lock doesn't do anything.
I've tried swapping out a different keyboard bypassing the kvm but that freezes the display as well.
If I press ctrl alt del while frozen the missing messages and typed keys will show up and the system will proceed to reboot.
I just turned off the automounter to see if the problem goes away but this may take some time to troubleshoot that way.
Was happening in 10.3 and still happening in 11.0-RC2
