Whatever is going on here it's KVM-related, not the FTDI box. That's an interesting issue all on its own but one that may be rather difficult to solve -- let's toss this thread and I'll start a new one when I can start chasing the KVM issue -- that's one that's not good as well, but I will check across OS revisions and see if it's limited to 9.x or whether it shows up on other, older releases as well first. -- -- Karl Denninger /The Market Ticker ®/ <http://market-ticker.org> Cuda Systems LLC _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
