Description Curtis Hamilton 2019-01-19 14:38:06 UTC
Attempted to install 12.0 Release on PowerMac G5 Quad using DVD and CD created from iso images ftp'd from freebsd.org.  Both boot into black screen.

I also attempted to build kernel from source and upgrade FBSD 11.1, with similar results.
Comment 1 Dennis Clarke 2019-02-07 18:05:56 UTC
While I do understand the frustration of downloading a "release" DVD
or CD install image and then receiving a less than perfect result
it should be said that the Apple PowerMac G5 Quad ( and similar ) is
an artifact of historical computing machinery interest and not a
current system architecture.  Whereas one may also claim that the IBM
Power architecture is very current and of very significant interest.
This does mean to say that the now ancient IBM RS/6000 Model 7317 is
not to be considered a production class machine. It was based on the
now twenty year old IBM PPC 604e and it is a fascinating system to 
perform experiments with but merely as an artifact. A reasonable and
even modern software system with very modern ZFS implementation would
be nearly impossible to run effectively on such hardware. The more
fascinating IBM PPC 970MP based Apple PowerMac G5 11,2 models are now
well over a decade old and face a similar problem. They are simply not
at all to be considered "production" class or "tier 1" type systems.

A lot of work has happened to keep such machines runnable in various
software projects and they even provide interesting data regarding low
level compiler functions but extensive testing simply is not possible
for any variation of "production" or "tier 1" level functions. Myself
and Justin Hibbits and others have done fairly extensive testing of
the FreeBSD release candidate DVD images and found that some minor
adjustments to the boot loader stage are required in order to get a
reasonable installation to work. For an example please see : 


At this time there should be a warning on the FreeBSD PPC project page
which illustrates that systems such as the Apple PowerMac G5 and even
older IBM RS/6000 units may not work as expected. A more modern class
of system such as the IBM POWER9 based Talos would be expected to work
as a very reasonable day to day unit and yet it is still "tier 2".

Actually .. these things may happen as r343862 iso dvd is not
bootable at all on that hardware.
Comment 3 Dennis Clarke 2019-02-09 08:28:20 UTC
I have done a test and neatly installed 12.0-RELEASE r341666 GENERIC
on a PowerMac G5 quad 11,2 thus :

I have tested with usefdt=1 and I see a kernel panic.
Given that I had to capture the panic data from usefdt with
a camera I will doucment that tomorrow.

Comment 4 Dennis Clarke 2019-02-09 18:26:28 UTC
I think we could re-release another dvd install image with
a loader.conf config that sets kern.smp.disabled=1 as a manner to 
deal with troublesome install hardware.
Comment 5 Curtis Hamilton 2019-02-09 19:26:10 UTC
Maybe it just the system I'm using, but setting kern.smp.disabled=1 does not work at all.   This applies the 12-RELEASE r341666 ISO or any earlier candidate releases.  

Through trial and error, I've only been able to get snapshot head r341614 (13-CURRENT) to boot, as previously noted by Mark Millard.

Any ideas?
Comment 6 Mark Millard 2019-02-09 19:48:33 UTC
(In reply to Curtis Hamilton from comment #5)

You might want to report how much RAM for the system showing the
problem. I'm not aware of anything else likely to contribute to
variations for the G5 4-core (system total). I'd reported in list
messages for 16 GiBytes and 12 GiBytes when requested. Also for a
2-processor (one core each): 8 GiBytes.

Almost all my activity has been with the 16 GiByte case.
Comment 7 Curtis Hamilton 2019-02-09 21:53:02 UTC
(In reply to Mark Millard from comment #6)
The system I'm using has 16 GiBytes RAM.
Comment 8 Sven Siemsen 2019-04-06 13:06:49 UTC
Same for me. Power Mac G5 quad, 16 GB

Yesterday, I did a buildworld and buildkernel with from releng-12.0 with the same result (black screen)
