Red Hat Bugzilla – Bug 483203
net/ipv4/tcp.c:1361 tcp_recvmsg+0x1f4/0x8da() (Tainted: G W)
Last modified: 2009-12-18 02:44:50 EST
Description of problem:
The network is wholly unstable on my laptop. This will manifest in userspace as dns lookups that don't resolve, failed transfer, slow transfers, and occasionally in the kernel as segfaults.
Version-Release number of selected component (if applicable):
Always reproducible, but fail occurs in different forms.
Steps to Reproduce:
1. Star a large transfer over any network device.
2. The transfer will be slow or fail.
3. Occasionally, the kernel will segfault.
Failing network, kernel panics.
No kernel panics.
I've had different experiences with different wireless drivers (ath5k, madwifi) and the r8169 driver. Both will fail at different frequencies and under different loads, but a kernel panic is always the result of long term use.
I've done a few memtests with the Fedora 10 Live CD, and so far nothing erroneous has shown up. Much of my searching for a solution will point failing hardware, but I've had the motherboard/processor/wireless card replaced, and this problem persists.
Attached is a kernel trace that shows up consistently among all drivers mentioned.

Sorry, I'll use the kerneloops program from now on.
Hi, after replacing the network card (twice) I found out this is a hardware vendor issue. I'm sorry for wasting your time.
I had the same exact problem. I was able to resolve it by downloading the sk98lin driver from marvell.com for my Marvell gigabit card, instead of using the default sky2 driver.
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
