I am using netbsd-1-6 kernel (as of yesterday's source) under i386.

I received:

   ex0 at pci0 dev 18 function 0: 3Com 3c900-TPO Ethernet (rev. 0x0)
   pci_intr_map: no mapping for pin A (line=ff)
   ex0: couldn't map interrupt

I read a posting saying this may mean that the system firmware didn't
configure an interupt for the device.

The card does work under another operating system.

I use this NIC successfully with NetBSD/i386 1.5.3 many times. Scratch
that ... now under 1.5.3 I receive the same message without "(line=ff)"
part though.

Does this mean that the NIC is going bad?

Thanks,
