Network freeze: ifdown/ifup sequence needed to clear network hang
Last modified: 2007-11-30 17:11:16 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: 1. 2. 3. Actual results: Expected results: Additional info:
The fedora-netdev kernels are available here: http://people.redhat.com/linville/kernels/fedora-netdev/ Please give those a try and post the results here...thanks!
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 up. 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.
Please attach the output of running sysreport soon after such a lock-up...thanks!
Closed due to lack of response. Please reopen when the requested information becomes available...thanks!
