Still, what leaps out at me in your verbose lspci listings (below)
is that the card with PCI ID 0a:0a:[01] (IRQs 177/193) is showing
up while card 0a:0c.[01] (IRQs 217/225) isn't showing up at all.
I don't understand why each card is getting two IRQs, but I'd
expect to see something like
ttySX at I/O 0xXXXX (irq = 217) is a 16C950/954
show up in your dmesg. Instead, all the ttySX listings from your
dmesg have IRQs from only one of the cards.
Yes, that is the problem. In another reply, someone mentioned a
kernel configuration option that may be limiting the number of serial
ports, which I'll be looking into.
Have you verified that each card works properly if installed by
itself, without the other?
Yes, they both work fine in either PCI slot.
