Hi,

I have the same symptoms as described. My system is also a Dell
Latitude D620 with wireless and wired network interfaces. Behavior is
that immediately after reboot my CPU is pegged by the system process
and the memory utilization is 1.5GB and climbs to 2GB where my machine
grinds to a halt. This takes about 60-90 seconds.

My network devices from the Device Manager:
- Broadcom NetXtreme 57xx (5752 actually) Gigabit
- Intel(R) PRO/Wireless 3945ABG Network Connection
- Juniper Network Connect Virtual Adapter

SysInternals process explorer seems to show that one thread in the
System process with a base address showing NDIS!NdisInitializeWrapper
is dominating CPU and massive Ctx switch rates.

I don't believe that a definitive fix was found in this thread.
Please reply/respond if you knwo of one.

Thanks,
Olaf

Hi Olaf,

the fix for me was to delete the physical network adapters in device manager, and to let them reinstall themselves. I had to repeat it a few times before it worked.

Riccardo,

I had exactly this problem on a Sony with Intel 3945abg WiFi. Go to the
Intel web site and get the latest drivers for this card. There is a bug
documented on the Intel site that exactly matches this problem. I've
installed the latest drivers and not had the problem since. See
http://alquistconsulting.blogspot.com for a full description. It's really
annoying that neither Microsoft update nor Sony update offer this upgrade. It
has taken me months to track this down.
