Description Panos Kavalagios 2010-09-10 06:27:05 UTC

Description of problem: Kernel module sky2 causes kernel oops when a high
network traffic is performed.


Version-Release number of selected component (if applicable): kernel-2.6.34.6-54.fc13.x86_64


How reproducible: Under high network traffic. A big download would be fine.


Steps to Reproduce:
1. Download a big file
2. Wait a couple of minutes
3.
  
Actual results:
eth0: hw csum failure.

Expected results: The ethernet controller should have worked even on high load


Additional info: This is the come back of bug 514693, duplicated to bug 574455 for Fedora 12. The workaround to restore the Internet connection is to remove sky2 module and re-insert it:

# rmmod sky2
# modprobe sky2

This is a very irritating problem following Fedora installations since Fedora 11. Downloading of a big file is nearly impossible. You have to retry several times by saving the partial content.

This looks like a hardware problem to me.

What mobo do you have? You seem to be the only person with this problem.

Comment 2 Panos Kavalagios 2010-09-10 14:40:54 UTC

I've got an ancient Intel Desktop Board D915GEV, with a sexy Intel(R) Pentium(R) 4 CPU 3.40GHz CPU with 4 GB RAM (only 3 something the mobo sees):

And this is my PC at work!
