 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.
