It would have been good if you had give the URL for the Reddit post, in
case there was more information in it or other people replied.

This is not good.  Unexpected things are likely to happen and seem to be
happening.

Irq 6 seems weird to me.

You should dump the config space with pcictl(8) or perhaps a kernel with
"options PCI_CONFIG_DUMP".

What does "Later, the MAC appeared" mean?  Did you reboot the machine?  Did
you power cycle it?

Getting watchdog timeout messages suggests that there's something wrong
with interrupts.

The DFE 530TX+ was a popular card 20 years ago and I seem to remember it
worked quite well.  There are even two dmesgd reports for netbsd:

Maybe you should also look at pcibios(4) for a machine that old.
