    Dear readers,

    As mentioned on http://teg.homeunix.org/sis900.html and
    http://www.latzinator.com/acer_aspire_1705SMi.html there is a problem
    with bandwidth for the SiS900 onboard NIC. I allways use vanilla kernels
    and I'm having had this problem from 2.4.22 to 2.4.24 and from 2.6.2 to
    2.6.6.
    The symptom is easy to explain. I connect the PC to a 100MBit switch and
    no matter which method of transfer (ftp, scp, samba, nfs) I use, I get a
    maximum transfer rate of less than 400kB/s. By accident I found a dirty
    workaround that might be a hint for some tech savvy hackers: if I force
    the NIC to use halfduplex (allthough it's connected to a switch) it
    works like expected (7-8 MB/s).

    The only help I can be is that I can test new kernel drivers and send
    you feedback.

    Any help highly appreciated,

    Thomas Latzelsberger

    FYI:

    about the Linux I use:
    gentoo with vanilla kernel. no additional kernel patches.

    hardware:
    Acer Aspire 1705SMi, I run the P4 without HT (thus, no SMP related issue)
