You should run 'rtl8139-diag' to see the chip state as this is occuring.
0c Transmitter and receiver enabled (normal)
0005 Interrupt status -- RxOK and TxOK interrupts are raised.
Well, that seems to the problem: the interrupt line is broken/blocked.
If you had been running a 2.2 kernel you would have seen a message that
described this, but detecting blocked interrupt lines is difficult with
the 2.4 kernel.
The bug here is likely the APIC IRQ line mapping.
