[Bug 24776] Re: ipw2100 - "Fatal interrupt. Scheduling firmware restart."

[Stefan Wagner]

I can confirm this bug for T41 with Ubuntu 8.04 LTS, since about one
week.

The wlan is open and router is an arcor-easy-box a800. The second laptop with ipw2200 works fine. Since about one week the connection is often dropped, but most times I can reestablish it, but often for a few minutes only - then the connection is dropped again. 
The distance to the box is a few meters only. The neighborhood is covered with foreign WLANs (all of them wpa2-secured). 
But this isn't new and the problems didn't exist for the two months before. (before that, I didn't used wlan, but classic eth).
