Comment # 7 on bug 1206767 from Larry Finger

One thing to try would be adding a 'sleep 10' line before the 'modprobe -v'
line in the "post" section of the "sleep_..." script. That will give the system
time to stabilize before the computer loads the wireless connection. One other
thing to do is enter a 'sudo dmesg -w' command before putting the computer to
sleep. After the GUI comes up, make that terminal have the focus before the 10
sec delay is up. I do not think the computer will hang, but if it does after
the 10 second delay, then we will have some debug info.

One problem that I had not considered is that openSUSE does not build
netconsole in their default configuration. If the above does not work, and you
are willing to build your own kernel, then I can supply instructions for the
next step.
