In a completely unrelated note, the upgrading of my Fedora Core 5 Thinkpad T42 to kernel 2.6.17-1.2139 has broken wireless (again). Any attempt to use NetworkManager with it causes ipw2200: Firmware error detected. Restarting. to be seen in the dmesg. However, if I run wpa_supplicant manually and then dhclient, it works.
I’m really looking forward to the day when all this is fixed, although I suspect wireless is such a bleeding edge problem space that the day won’t be coming soon.
