[kwlug-disc] Older PC not booting Linux ...

[Khalid Baheyeldin]

I have an older PC with an AMD Athlon II X4 635 CPU, and 4GB of RAM.
There are no expansion cards (PCI, AGP or whatever). The display is
on board with a VGA output.
Testing the memory passes with no issues.

It was working at some point before I shuffled my home servers back in
January.

Now that I am trying to repurpose it, I am not able to get it to boot at
all.

Using Xubuntu 64bit 20.04 (also with 22.04), and even Finnix (Debian based
small USB rescue distro), it displays the initial boot stuff, then the
display
freezes, and there is nothing happening.

When I removed the "quiet splash" parts from the boot command line, I found
the following errors:

pci_bus 0000:02: extended config space not accessible

Then a few more innocuous lines with 0000:00:14.4 without issues, following
by this:

pci 0000:00:15.0: bridge configuration invalid ([bus 00-00]), reconfiguring

Then the PC freezes at this point ...

I searched various search engines, and there is not much there, apart from
trying pci=nommconf, which I did with the same results.

Is this a hardware issue? If so, which component?
If it is not hardware, what else can it be?
