When coming back from s2disk I have to:
. ifdown wlan0
. rmmod iwl3945
. modprobe iwl3945
. ifup wlan0
In the mean time, I use my notebook in a BSS environment. As soon as the notebook is out of the range of the AP on which he is connected, he looses
the wireless connection instead of switching to another AP in his area. I made the same test with an eeePC (Lenny) and a Nokia E65 phone, they work
correctly meaning that they switch to the other AP.
I hadn't those problems with a 2.6.26 kernel.
can you test 2.6.29-rc7 from buildserver see trunk apt lines
http://wiki.debian.org/DebianKernel
Done.
dh@listryx:~>uname -a
Linux listryx 2.6.29-rc7-amd64 #1 SMP Fri Mar 6 00:37:22 UTC 2009 x86_64
GNU/Linux
. wake up after s2disk doesn't work anymore eg xorg freeze, no keyboard.
Don't think it come from iwl3945
. working in BSS environment still doesn't work
It change something from 2.6.28: when I ifdown wlan0 I can get ifup
working correctly without rmmod/modprobe iwl3945 module.
More interesting is this from dmesg:

What means "not using net_device_ops yet"?
