FreeBSD 9 "gptboot: invalid backup GPT header" error (boots fine though)
...ing since it doesn't happen when I do it manually). So I
kept reOSing it doing different things and ultimately found shell-based
manual partitioning worked fine.
However, I see the following error right before BTX comes up (and did
previously when using the installer's partition GUI):
gptboot: invalid backup GPT header
The machine boots fine, so I'm not stuck .... but it is an annoyance for
an A-type sysadmin like myself. Even if its superficial I dislike
setting up a client's machine to generate "errors" on boot, especially
without an explanation or understanding...

FreeBSD 9.0 - GPT boot problems?
...he BIOS from version P01-A3 to version P01-A4 (the newest available), still no dice.
If I use the usb stick I installed from, I can select the boot device, and actually boot from it, so there doesn't seem to be anything wrong with the SSD.
I tried:
kg-vm2# gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ada0
bootcode written to ada0
in case there was something wrong with the bootcode, but I still get the message "ERROR: No boot disk has been detected or the disk has failed."
gpart shows this:
root@kg-vm2# gpart show ada0
=> 34 250069613 ada0 GPT (119G)
34...

The gpart bootcode command is quite apart from and unrelated to (as far as I can tell) the EFI partition.
I think the EFI partition is supposed to be the first partitio...

Reinstalling boot blocks on a ZFS-only system
So, I've long known and it makes sense that when you're booted from a ZFS volume, you can't mess with the boot-loader. And, I know a few months ago I had a set of commands I would use when booted from a CD that would initialize the network and copy the "release/boot" from somewhere else so that I could install bootblocks and boot-loaders from more recent code. Sadly, I

Dell Perc 6 disk geometry problem with RAID5 (both 6.3 final and 7.0 RC1)
Hi,
We bought a new Dell PowerEdge 2950III with Perc 6/i and have the disk
geometry problem using 6.3 final or 7.0 RC1. Seems that we are not alone at
least one guy has similar problem reported earlier:

I was reading the mailing list and found that some of the people are happily

Problem with /boot/loader
Hello,
I have a problem with loader. I recently upgraded from 6_rel to 7_rel.
Now when I install world there is a problem booting.
Here is what I do:
cd /usr/src
make buildworld
make buildkernel KERNCONF=BLACK
make installkernel KERNCONF=BLACK
At this point I can reboot and all is good. After boot I install the new world:
cd /usr/src
mergemaster -p
reboot into single user mode
cd /usr/src

Collecting entropy from device_attach() times.
Hi.
I experimented a bit with collecting entropy from the time it takes for
device_attach() to run (in CPU cycles). It seems that those times have
enough variation that we can use it for entropy harvesting. It happens
even before root is mounted, so pretty early.
On the machine I'm testing it, which has minimal kernel plus NIC driver
I see 75 device_attach() calls. I'm being very careful

IPMI serial console
Hi all,
A recent thread inspired me to try getting a proper serial console working on a Supermicro X9SCL motherboard with IPMI.
However I find that while I see loader messages and the getty I enabled after boot I don't get any kernel messages which does somewhat limit the utility..
The BMC creates COM3 (/dev/cuau2) which works with getty. I modified /boot/loader.conf like so..
