O.K., here is a  funny bootverbose test-session (using Original rpi-power adaptor 3A & UPS(Uninterruptible power supply ) :

Hot-Plugging the HDMI-Display freezed the system ….

Next cold boot shows  gen0.2: <Unknown > at usbus0 (disconnected) again … system seems to be freezed again….
Next coldboot after hardreset WITHOUT UART : same :  gen0.2: <Unknown > at usbus0 (disconnected)
( no working keyboard ) .. plugging back the UART.. see again :
pcib0: bcm_pcib_alloc_resource FAIL: type=3, rid=36, start=00000000f8000000, end=00000000f80fffff, count=0000000000100000, flags=40
..shutdown -h now.. 
Next try with changing the HDMI-port but same Adaptor :
After pressing keyboard suddenly da0-detection : da0 at umass-sim0 bus 0 scbus0 target 0 lun 0
and system-freeze …
Next hard reset …. Goin`full risk to burn my new display :-) Ha Ha …changed HDMI-cable…
No HDMI but super strange console-output with loops like this(and the next system-freeze) :

Next hardreset.. changing the HDMI-port(used other mini-dmi->HDMI- adaptor-cable)… got hdmi-output :
Pressing ENTER on the keyboard: login: ugen0.2: <Unknown > at usbus0 (disconnected).. system freezed again …
….plugging back to other HDMI-port(got output means I failed in connecting the adaptor correctly:-) …
Next system freeze : ugen0.2: <Unknown > at usbus0 (disconnected)…

To the opposite of the day before yesterday: 
Tonight there was absolutely no way to get the keyboard to work what let me assume that the filesystem (or u-boot)
or eventually some hardware-chip was  „attacked“ by these tests… 

So at the moment I would be more careful recommending normal users to do more testing before fixing bugs in drivers (or U-Boot or elsewhere) better. For that reason I`ll better wait with Wiki-recommendatios….
This is only for the for the really crazy of us who are not afraid of toasted boards or something else ;-)
So for the really crazy of us( I guess near 100 percent;-)   : please help us debugging !
