hello,

I am running a custom compiled 2.6.34 (fedora 12) on a hp nx7400 with
a Intel Pro Wireless 3945 card, the card works fine and connects to a
WEP secure wireless connection on my router. But after some time
network manager starts reporting that the wireless access point is not
available anymore and tries to reconnect to the network, though the
network is still available, it fails to detect the network , I have
not been able to reproduce the situation conclusively, seems to be
happening randomly ... here is the tail from "dmesg" which looked
suspicious :
(btw, I also faced the same problem earlier when I was running RHEL
beta 6.0 on the same machine)
