I have tried several times to install FreeBSD 14.0-CURRENT powerpc64 BE on my Talos II,
unfortunately without a positive ending. I have tried several versions 220617, 220701, 220708
and each time the system installed without error messages but Petitboot did not see the system.
Yesterday I tried the 220715 version and also did not have success. So I decided to take a closer
look at it and found that the installer incorrectly fills /boot/etc/kboot.conf:

Code: [Select]
='/kernel/kernel kernelname=/boot/kernel/kernel vfs.root.mountfrom=ufs:/dev/nda0p2'

After changing the entry to the following:

Code: [Select]
FreeBSD='/kernel/kernel kernelname=/boot/kernel/kernel vfs.root.mountfrom=ufs:/dev/nda0p2'

I made the changes manually from the Petitbnoot shell. Just keep in mind that Petitboot mounts
read-only /boot by default. You have to unmount it and mount it with write permission. After the fix,
vi is helpful here, you need to unmount the partition and re-mount it read-only. Without this last
step and after direct loading of the system, the changes will not be saved. You have to repeat
them from the system level.

One final note about ZFS, by default FreeBSD on ppc64 does not support this filesystem. This
is due to Petitboot limitations. You have to compile the system yourself. The recipe can be found
here "FreeBSD/powerpc64 (POWER9) with ZFS on /".

Currently my Talos II is compiling the kernel on a single core since yesterday. I did it consciously
to have a benchmark  ;)

General OpenPOWER Discussion / Forum signature size.

Can you change the size of the signature from 300 to 1024 characters? Manipulating the colors of characters quickly exhausts this limit ;-)

Operating Systems and Porting / Fedora 36: Kernel upgrade problem.
« on: July 11, 2022, 02:16:48 pm »
I recently upgraded Fedora 36. DNF showed me that he has installed a new kernel 5.18.10. Unfortunately, petitboot still only sees kernel 5.18.7 after a reboot. Do I have to do anything else special?

I tried the [PPC] /v2.9112.521/2016-06-13 version for Linux but it it doesn't work ;-)

Talos II / Installing the system on a Samsung 980 Pro SSD 1TB
« on: June 24, 2022, 04:33:11 pm »
Heya everyone,

At the outset, I would like to mention that I waited almost four and a half years for my own Talos II station. This whole story deserves a separate article
and I even started to prepare for it. But I figured I needed a working base first to be able to write anything on my new toy without going back to x86 too

For my first attempt, I decided to install FreeBSD 13.1 on two Samsung 980 Pro SSDs. I put the disks into the Highpoint SSD7502 controller. As expected,
I saw two separate drives as a possible installation location. Unfortunately I couldn't use ZFS to do RAID although it was stated on the FreeBSD website
that ZFS runs on the powerpc64 platform. I marked the first disk as the target and decided to partition it. Partitioning worked, I chose UFS as the root
filesystem and FAT as the system for the kernel partition. I started the installation. This operation did not produce the expected results, a process crashed
while trying to unpack base.tar.xz.

So I thought that the problem may be the raid controller, because FreeBSD does not have a dedicated driver for it. So I replaced the controller with a simple
ICY BOX M.2 NVME to PCIe 4.0 adapter: IB-PCI208-HS. Unfortunately, this operation did not help. I still couldn't install the system. So I decided to try the
powerpc64le version. Surprisingly, this version installed and I was even able to boot the system. However, my joy lasted only a short time, when I tried to install
packages, the system crashed.


Second try:


I found information on the network that there were performance problems with the first Samsung 980 Pro disks for PCIe 4.0. I decided to replace
the firmware. I moved the adapter to Dell OptiPlex 7040 and updated the firmware:





After this operation, I decided to reduce the system installation time and focus on disk tests. I have successfully installed FreeBSD on a USB key.
With the key, the system worked flawlessly. Unfortunately, attempts to access the SSD drive always end up in the disappearance of the device.
Fortunately, the system did not lock up anymore.



I was disappointed. I tell myself I'll try Linux. It's probably much better here. I have installed the distribution that I use professionally on x86, AlmaLinux 9:


Installation seemed to go smoothly, but there were momentary system freezes. I looked at the logs and my worst expectations came true:


After five such errors, the system stops operating the device and further normal operation becomes impossible. Usually, full freezing of work occurs
within a quarter of an hour.

Of course, I have no more ideas what to do with it. Any help is appreciated...

PS. Sorry for the lack of direct images, but I'm having trouble providing the correct DropBox preview links.
