 |

Initially I thought this problem was due to lack of support for my (Soyo Dragon Plus!) onboard NIC. I enabled Via Rhine Support in my kernel and everything appeared to be OK. The inteface came up clean, nothing odd in my dmesg and I could do anything that required network connectivity. However things would just hang periodically (e.g. playing enemy territory online, irc). I have checked all my system logs and nothing stuck out. So than I decided to disable the onbaord NIC and put in a 3com 3c905x in. Enabled boomerang support and off I went. The thing is, I am still having the exact same problem. The only other thing I can think of, is that some other component in my system is causing the problem. I am running raid0 with 2 40gig maxtors using the promise ide raid support. I am also running the onboard 6 channel C-Media sound device. Video card is Nvidia Ti4200.

Using gentoo-sources
Has anyone else encountered this? If so how did you fix it? Can someone recommend some troubleshooting tips? |

If you suspect your network connection, you could run a ping while you are playing/ircing, something like this should do:
| Code: |
#!/bin/sh
host=$1
while true
do
date "+%c: `ping -i 1 -c 10 $host`" >> ping.log
sleep 2
done
|
If there is a hang, note the time and look through your log file, especially for lost packets. Try pinging your Gateway and for example your IRC Server. Perhaps it's a problem of your ISP.

Thanks for the suggestion. However I know its not a packet loss problem, because I can play games online, irc and anything else flawlessly on my laptop. ( on the same LAN)
Any other ideas? |

Two things to suspect:
1) Improperly configured DNS can cause strange hangs.
2) You say it is a laptop, perhaps it is an ACPI/APM problem.
Hope that gives you a starting point. |

I'm having the exact same problem. Only mine is with a wireless card (Orinoco Gold Card). I'm using a desktop (it has a PCI to PCMCIA converter). I use gentoo-sources as well. A more detaile description can be found here:

Can't figure out the problem. I tried to boot the kernel with pci=noacpi with no luck. |
