When I install FreeBSD 10.0 via an ILO/IPMI/KVM-mounted .iso image, the machine usually hang in very much the same manner as described in this thread, just when it is supposed to reboot. The problem seem to be related with the USB system, which simply won't die, and the machine will therefore never reboot itself. (I guess the USB system is busy with my virtual CD/keyboard/mouse) Workarounds: press the reset-button, and the machine will reboot just fine... or first set the sysctl hw.usb.no_shutdown_wait=1 before the installer reboot the machine. So if someone has a machine where the problem can *always* be reproduced, test the sysctl command above just to see if the USB system is the real reason for the hang and the subsequent dirty filesystem. /Elof -- You are receiving this mail because: You are the assignee for the bug.
