Bug 50213 – Kernel hang on network traffic

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Peter `MathFox' Roozemaal 2004-05-06 05:43:40 UTC]

I am running an Athlon64 (3200+) on a Gigabyte K8NNXP motherboard (nForce3 chipset). When connecting the ethernet (100 Mbit) to the LAN1 (Gigabit Realtek 8169) port I can hang the system by sending a significant amount of data to it. When the ethernet is conected to the LAN2 (nVidia) port the system accepts the data I throw at it nicely.

Reproducible: Always
Steps to Reproduce:
1. Boot system, configure LAN1
2. From another system on the network: scp bigfile testsystem:

alternative 2. run rsync aganst a fast server
Actual Results:  
After a few 100's of MB the transfer stalls; testsystem hangs and needs a hard
reset to recover. (It looks like the keyboard driver is somewhat alive, virtual
console switching fails)

Expected Results:  
run without a hitch

[Comment 1 Peter `MathFox' Roozemaal 2004-05-06 05:46:13 UTC]

N.B. the kernel on the 2004.1 liveCD has the same problem.

[Comment 2 Tim Yamin (RETIRED) 2004-06-04 11:49:31 UTC]

Are you able to reproduce this issue on development-sources?

[Comment 3 Peter `MathFox' Roozemaal 2004-06-11 13:54:50 UTC]

With development-sources 2.6.4 (the latest ~amd64 version) the kernel doesn't get past mounting the root partition read-write.

[Comment 4 Peter `MathFox' Roozemaal 2004-06-13 07:51:20 UTC]

This bug is gone with a development-sources 2.6.7-rc3 kernel.

[Comment 5 Greg Kroah-Hartman (RETIRED) 2004-06-21 11:39:18 UTC]

then let's mark it fixed :)
