Wireless networking - bcm43xx making pc crash

Sloebervos

Hi,

I've got a pc running gentoo with a bcm43xx based network card. Now recently, I started getting problems with the pc. Everything works fine, but after a while the pc isn't responding anymore. I need to hard reset it and it works again for a while.

This is what I see in the logs :

Oct 10 21:05:45 frontend bcm43xx: Controller RESET (TX timeout) ...
Oct 10 21:05:45 frontend bcm43xx: Controller restarted

uname -a :
Linux frontend 2.6.18-gentoo #2 Sun Oct 8 18:24:10 CEST 2006 i686 AMD Athlon(tm) XP 2500+ AuthenticAMD GNU/Linux

I tried 2.6.19-rc2, but the result is the same.

I don't recall any hangs when running 2.6.17. Is this kernel related?

might be so...
I use 2.6.17-r8 and have no problem...
---------------
just to be sure if it is the wireless,
disable all modules with rmmod and then run your computer for a few hours...

Okay,

The pc isn't hanging anymore, but the card still loses connection.

dmesg shows this :

NETDEV WATCHDOG: eth1: transmit timed out

iwconfig :

lo no wireless extensions.

eth0 no wireless extensions.

eth1 IEEE 802.11b/g ESSID:"juve" Nickname:"Broadcom 4306"

eth2 no wireless extensions.

so apparently the wireless connection gets restored but the ip is lost. I'll switch to fixed IP and see what it gives.

.:chrome:.

do you have loaded the firmware?

yes,

Everything is loaded perfectly and it works for some time, and all of a sudden the controller resets...
