I tried on other computer with FreeBSD 6.1 and 7.0-STABLE snapshot from march- same results. Something is broken on FreeBSD side- strange thing is that when I turn power down on cisco box and turn in on again then I see scrolling text from cisco gear but there is no feedback to keyboard activity. How to debug this issue? Andrei
