[zd1211rw] suspend/resume failure

[Id2ndR]

This append with zd1211 module loaded (used by my wireless dongle).

The computer can go to sleep and resume without the dongle but won't go to sleep with the dongle plugged in.

This bug is a duplicate of Bug #274734 but it add files automatically reported by apport.

Workaround :
- Create a file in /etc/pm/config.d/unload_modules and add the following line:
SUSPEND_MODULES="mac80211 zd1211rw"
- You'll also need to make this script executable, which you can do using:
chmod +x /etc/pm/config.d/unload_modules

I tried pm-suspend from VT1 : the screen goes empty with a blinking dash. However there wasn't any messages that appears in any VT.
I still was able to switch to different VT (til I didn't go to VT7) and pressing Enter made line appears below the pm-suspend command.
I also try :
- Ctrl+C and it made appears ^C but doesn't stop the pm-suspend command.
- unplugged and plugged any usb device but it was not recognized by the system after being plugged again.

Additional tests from https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume :
- I tried the no_console_suspend kernel option : no difference.
- I used "setfont /usr/share/consolefonts/Uni1-VGA8.psf.gz" : the text goes back to normal size when it showed the blinking dash.
- There is NO flashing caps-lock or similar.

Steps to reproduce :
- load zd1211rw module (even it you don't have the hardware
- try to suspend the computer : it won't go to sleep

This fix worked beautifully with my Jaunty install. I had been blaming it on the nvidia drivers. I have a HP Dv6000 with a faulty internal wifi/bt card, I replaced it with the cheapie zd1211 (belkin f5d7050 v4) and hard wired it d in. I decided to fully disconnect it and found it to be the cause, thanks for finding this guys.
