I never saw this message in earlier > versions of BSD. I'm running 5.2 now. I remember testing this or a variant of this patch; I have a: sis0: port 0x1000-0x10ff mem 0xf4102000-0xf4102fff irq 9 at device 15.0 on pci0 sis0: Ethernet address: 00:a0:cc:75:97:29 miibus1: on sis0 ukphy0: on miibus1 ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto I gather the chipset tries to compute or adjust some DSP parameter based on cable length, only it doesn't do the right thing for short cable lengths, so the fix resets the value to something which works better than the value the code would otherwise choose (absent this fix). -- -Chuck
