Comment 89 for bug 300693

I'm having the same problem with Karmic using 2.6.31-17-generic.

I have a T61i with the Atheros wireless (AR5212) chip set using the madwifi drivers ath_pci and ath_hal with wicd since I couldn't get the ath5k driver with NetManager to work with Karmic. It will not recognize my internal wireless card even though this same configuration worked perfectly in Jaunty.

The problem only occurs when connected using wireless. I can be on for days without an issue with a wired connection. No apparent information in the logs outside of the following:

The T61i is not responsive (locked up) with the blinking caps light.

I'm tempted to try the ath5k driver again but don't know if that will really correct the situation.
