Hello everybody! I'm using Linux from scratch. Kernel 2.6.13.1, ipw2200 1.0.6 and my Computer is a Medion Laptop (Medion 95500; the WLAN is Intel Pro/WL 2200 BG). First I wasn't able to compile ipw2200-1.0.6. After reading the fitting bug-report and installing ieee80211-1.0.3 I was able to build it. But when I tried to start dhcpcd on my WLAN-Device (eth1) it timed out. And went through everything, finnally adding QoS-Support to my kernel, hoping this would help. After rebooting the new kernel I tried the same as before, dhcpcd eth1, and yes, a beautiful kernel panic (Said something about no sync; did not find it in the logs, sorry). I was able to reproduce it every time I tried. After rebooting with the Kernel without QoS-Support it timed out again, but no kernel panic. Using Kernel 2.6.11.10 and ipw2200-1.0.4 WLAN worked fine. (But I had to update to 2.6.13 for other reasons) I don't know, wheater this is a kernel bug or rather a bug in ipw2200, so I decided to report it here. Would be great if you could help me use WLAN again... Sascha Schmidt
Please try comment #3 in bug 790.
Thank you for the fast answer. I tried the patch, didn't help. Was I supposed to re-add QoS-Support to Kernel and IPW2200-1.0.6? I also tried to use my WLAN with a static IP - it worked; but that's no solution; I cannot use a static IP in foreign WLAN Networks, only in my own... So, there seems to be another problem with dhcp and IPW2200. What role plays QoS in all this? At least it seemed to be in charge of the kernel panics?!?
Does bug 769 patch help with your case?
The Problem seems to be solved; running dhcp with WLAN works again; but I didn't try with kernel-support for Qos by now; thats not that important to me. Thank you for your help.
