Bug Description
Since the upgrade from Jaunty, wireless is no longer available after a RAM suspend recovery. I am using x86_64 karmic on a VAIO VGN FZ18M
nickolai@nexus:~$ uname -a
Linux nexus 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux
the NetworkManager applet displays a "device not ready" message for wireless.
the kernel log is flooded with messages like
iwl3945 0000:06:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0xFFFFFFFF
reloading the module with modprobe does not solve the problem. i suspect this is what is generated :

attaching full kern.log. the resume time when the error occured is around 1315.

Happens to me to (same problem with 9.10 that didn't happened on 9.04, same kernel log), on the same laptop model (Vaio VGN fz18m.)
