I know this is a long shot....  But maybe there's a cold solder joint
on the NetMOS dual UART board?

/me happily using two PUC devices right now on his 4.9 box:

puc0: <Moxa Technologies, C168H/PCI> port 0xa400-0xa40f,0xa800-0xa83f,0xb000-0xb07f irq 5 at device 9.0 on pci0
puc1: <Titan PCI-800H> port 0x9800-0x981f,0xa000-0xa01f mem 0xe1000000-0xe1000fff,0xe1800000-0xe1800fff irq 12 at device 10.0 on pci0

The moxa is a 8 port monster, and the Titan is a 4 port monster (yes,
I do need 12 serial ports for all the machines I act as serial console
for, well maybe only 10).  Maybe I have too many machines...
