Hi,

Just about every machine I have seems to hang after running =
freebsd-update and doing a reboot. The last message on the screen is =
"All buffers synced=E2=80=9D and it just freezes.

This happens when doing a freebsd-update and going from 10.0 to 10.1, =
but also when doing a fresh 10.1 install and using freebsd-update to get =
the latest -pX security patches. As soon as I reboot the machine, it =
hangs.

I=E2=80=99ve tried it on several different HP ProLiant models, on Intel =
NUCs and on VMware virtual machines. Same phenomenon everywhere. It=E2=80=99=
s really easy to trigger: just install 10.1, use default settings =
everywhere, freebsd-update fetch/install, shutdown -r now and BOOM. It =
hangs. I think I=E2=80=99ve seen it on =1E=1E=1E=1E=1E30 servers or so =
now.

Everything works like it should after the initial hang tough - no matter =
how many times I reboot it completes the reboot cycle just fine.

I=E2=80=99ve seen several people (mostly on IRC) mention this problem, =
but no solution.

Is anyone working on fixing this?
