Comment 1 John W. Linville 2007-10-01 10:50:11 EDT
Can you replicate this with the kernel?
Comment 2 Need Real Name 2007-10-01 16:50:11 EDT
I have already, didn't work. Or should I say it works sometimes, very
intermittent. I would like to semi close this bug as I am trying to upgrade to
Fedora 8 Beta 2 and wont be able to do any testing, maybe reopen if its still a
bug in 8?
Comment 3 John W. Linville 2007-10-16 13:52:58 EDT
Is this still a bug in current fedora 8 kernels?
Comment 4 Pawel Salek 2007-10-19 18:15:52 EDT resumes wlan just fine *AS LONG* as the configuration is set via
ifcfg-wlan0. NetworkManager still cannot restore its configuration on wake up
for me (but that's another bug). This is with Dell D630.
Comment 5 Pawel Salek 2007-10-20 16:21:47 EDT
I see though one glitch with when I use the killswitch, "rmmod
iwl4965 && modprobe iwl4965" is required to reenable the wireless interface.

Closing as RAWHIDE...please feel free to open separate bugs for the issues 
mentioned in comment 4 and comment 5.
