Description Richard Woodruff 2005-11-11 20:02:10 EST
Description of problem:

 Network locks up on Dell Precision using E1000 driver.  After some use 
networking locks up.  The system will not respond to pings.  At a console window
on the machine a ifdown then ifup will clear the condition and networking starts
to work again.

Version-Release number of selected component (if applicable):

 started on 2.6.14-1.1637_FC4smp (and 638)

How reproducible:

Start up DIA on another machine.  Start editing a large diagram, zoom in till
large.  System locks up.  Now go to console and tweak networking and it
restarts.  At the console some gnome apps don't respond until the network
up/down sequence also.

Not very focused, but its something which didn't happen using eariler kernels.

Steps to Reproduce:

I booted the 2.6.14-1.1637_FC4.netdev.2 kernel and the same hang up happens.  
In the two times I tried, it actually happned faster, almost immediatly.

Using the 2.6.14-1.1644_FC4 it still happens but may take five minutes to lock 

In general the senerio I use to repoduce it is to use an Exceed Xterm on a Win 
System displaying from my FC4 box.  I can understand and expect the Windows 
side windows to freeze up, but not the Linux box's net usability.  I suppose I 
could run ethereal to see if one side was spewing packets... Top on the linux 
side doesn't show anything strange.
