    I am struggling with this somewhat soft error. I have Toshiba
    1410-S173 Laptop. I am having NetGear MA401 Wireless PC card and
    NetGear MR814 Wireless Router. I bearly got them working with RedHat
    8.0 (Linux kernel 2.4.20 with ACPI patch). The module for PCMCIA card
    is orinoco_cs

    However suddenly wireless connection is lost and I see ksoftirqd_CPU0
    process taking 90-95% processor.

    /var/log/messages shows entry
    eth1: Error -110 writing Tx descriptor to BAP

    If I restart the pcmcia daemon the things start working normally.

    Any ideas?

    Thank you,

  2. Update on this:

    I was suggested to upgrade the orinoco_cs driver that I am using.

    I was told download and install pcmcia_cs3.4.2 package as easier way to
    upgrade this driver on orinoco_cs driver development central on
    sourceforge. I did it but still the end to the problem is nowhere near.

    Any other ideas?

    Thanx for your time,

  3. Hi,
    Thank you very much for your suggestions and time. I think (and
    pray) that this thing works becoz it seems to be.

    Though I didn't exactly got the result after following your procedure
    but definately the suggestion of downloading the latest beta driver was
    helpful. I am posting this information for anybody who is having
    similar problems.

    Here is what I did:
    I downloaded latest orinoco_cs driver version 0.13e from

    copied it in my home directory:

    #tar -xzvf orinoco-0.13e.tar.gz
    #vim Makefile

    Change PCMCIA_CS=<blank> to

    //This step was necessary becoz I am using pcmcia-cs package. Presumably
    you will get "Card Services release does not match" error if you are
    using pcmcia package and miss this step.

    #make install
    #/etc/init.d/pcmcia restart

    Before compiling this driver I used to get the ugly "Error -110 writing
    Tx descriptor to BAP" message and ksoftirqd_CPU0 used to consume 95% of
    the CPU when I used to go to link
    "". After I upgraded,
    I didn't. So I am assuming I am better off than not upgrading :)

    Thank you all for helping me

    P.S.: Just a shameless promotion: If you have want more infotainment on
    how I installed wireless network on Toshiba Satellite 1410-S173 and
    lived to tell it; please visit my site on this subject
