Greetings,
I updated my system to 7.0 and noticed that when booting, there is an
error as follows.

If I let it boot the kernel, the system doesn't show all the booting
details, such as hardware information. I'll be presented with the
login and I am able to log in without any problem.
When I type reboot to reboot the machine, no output from the screen
but the machine will be rebooted without any system messages.
Here is the uname output.

I googled for a while but couldn't find any related information as to
why this happens and how to correct it. Thanks in advance for any
ideas!
When there is a major ABI change I install from scratch, rebuild my apps,
and move the data over from backups. This is infrequent, as in when I went
from 4.11 to 5.2.1, then again to 6.2, and lately with 7.0. I just don't
fully trust cvsup/csup upgrades between major ABI changes. I'm sure many
don't do this and have had no problems, I'm just wonky this way.
Yes, I rebuilt everything from source including all the ports and
their dependencies.I
I seem to recall something loader related in the list traffic some time
back, but since I've had no troubles in this area didn't pay much
attention. I currently have two machines on 7.0-Release, installed from
7.0-RC1, csup'd to RC3, and then again to Release without incident.
Did you try upgrading from RELENG_6?
One thing I would look at is the use of any optimizations in /etc/make.conf.
Particularly -Os -pipe or -O2 -pipe. If you have any optimizations such as
these, or CFLAGS/COPTFLAGS, try removing them and rebuilding world/kernel,
etc.
I wouldn't worry about the kernel as the kernel hasn't been loaded the
moment the error occurs.
As pointed out by Martin, it seems to me that something may be carried
over from 6-STABLE and is not compatible with the new 7-STABLE loader.
I don't think I use aggressive compiler options but anyways, this is
what I have in my /etc/make.conf. Thanks!!!!
