Ubuntu: Hibernate/Suspend to disk: Resume problem with ATI Radeon R7

On a new Lenovo laptop i had some issues with supsend/resume.
I installed tux on ice and the suspend process worked, but the resume just freezed after some seconds.

First step to solve this problem was to stop the graphics (/etc/init.d/lightdm stop) and try it again.

This attempt worked without a problem, so it was clear: the resume problem is a issue with the graphic card:

Debian dist-upgrade: Laptop suspends 30s after boot / startup

After i moved to jessie (Debian 8) my laptop moved to suspend to RAM about half a minute after startup.
There was no message in the logfiles and even worse the resume does not work at all...
The configuration for the suspend was in here:
/etc/systemd/logind.conf:
 [Login]
#NAutoVTs=6
#ReserveVT=6
#KillUserProcesses=no
#KillOnlyUsers=
#KillExcludeUsers=root
#InhibitDelayMaxSec=5

#SuspendKeyIgnoreInhibited=no
#HibernateKeyIgnoreInhibited=no
#LidSwitchIgnoreInhibited=yes
#IdleAction=ignore
#IdleActionSec=30min
#RuntimeDirectorySize=10%
#RemoveIPC=yes
After changing the lines "HandleLidSwitch" and "HandleSuspendKey" to ignore (more...)

Debian dist-upgrade: ipw2200 firmwares missing…

After the dist-upgrade the ipw2200 wireless chipset drivers are missing.
Grrrr...
No more internet access - so i had to use a good old LAN cable ;-)

The fix was very easy:
apt-get install firmware-ipw22x00
rmmod ipw2200
modprobe ipw2200
 and the wireless network is up again...

Two weeks ago i started a first experiment with translating strange articles by Google (see here).
This was the next snippet (from IT-BUSINESS), which was a little bit weird:
