NetGear MA401 PCMCIA Problem: ksoftirqd_CPU0 taking 95% CPU

Hi,
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,

regards,
Aditya Newalkar

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,
Aditya Newalkar

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

http://ozlabs.org/people/dgibson/dldwd/

copied it in my home directory:

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

Change PCMCIA_CS=<blank> to
PCMCIA_CS=/usr/src/pcmcia-cs3.2.4

//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
#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
"http://www.nvidia.com/content/drivers/drivers.asp". 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
