Low bandwidth or hangs with on Pentium 4 HT and SiS chipset motherboard

The problem, with a proposed (but non working) solution is described here. I received another report, with the same hardware. In this case there are no hangs, but the badwidth is limited to 400Kb/s. See this page for reference.

I found out that this problem is related to the PHY transceivers one (see below), so you should go there and read carefully.

I added the Altimata PHY chip to the list builtin in the driver with the help of Stuart Bennet, so, hopefully, this is fixed once for all.

Bad PCI device ID for SiS ISA bridge

The PCI device ID has changed between 2.6.3 and 2.6.6 kernel versions, this is not a bug but a feature, Mark M. Hoffman has an explanation in message 20040517160325.GA9997@earth.solarsys.private:

    It was this patch, which I wrote:

    http://marc.theaimsgroup.com/?l=linux-kernel&m=107939686916811&w=3

    The patch was necessary to enable the SMBus device (commonly used
    for hardware sensors).  It will cause SiS chipsets that claim to
    be 0x0008 but are capable of being 0x0018 to make the change.
    

For this issue a patch is available as sis900-isa-bridge-id (see below).
