Yeah - I've seen the same thing when rebooting - the cpu_reset message appears and there is a long delay before a reboot happens. I have no problems powering off though (shutdown -p). I've got a -current vm under 6.5.4 with 2 CPUs, host OS is Windows 7, that can take a while to reboot. I haven't timed it but 90 seconds from the message appearing is a good estimate. Since the disks should already be synced by that point, there doesn't seem to be any harm in just resetting the VM - I've done it a number of times and never had any issues. However, even on a real computer, there is a bit of a delay here - my Thinkpad T61 will sit there for around 20 seconds before actually rebooting. I have no idea how to even start debugging this kind of thing and it isn't a really big deal to me (I don't reboot too often and just use the workaround when I do), so I never reported it. -- Rob Farmer > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" >
