It has no com ports on the motherboard, but two on a PCI card:
puc0 at pci2 dev 1 function 0: NetMos NM9865 1 UART (com)
com2 at puc0 port 0: interrupting at ioapic0 pin 17
com2: ns16550a, working fifo
puc1 at pci2 dev 1 function 1: NetMos NM9865 1 UART (com)
com3 at puc1 port 0: interrupting at ioapic0 pin 18
com3: ns16550a, working fifo
That PCI card was installed only after the initial PR was filed
against NetBSD 5.1, so I doubt it is the cause of the problem.
The problem might be related to PR kern/46696, which also affects
this particular machine. The motherboard is an Intel DH67CLB3 H67.
