Public bug reported:
I made a bootable USB stick from the Ubuntu 11.04 beta 2 desktop-iso (AMD64).
When I boot it on my Lenovo U350, it imitatively crashes. The screen is almost
blank, but there are some unreadble text on the screen. The font is about
5x10cm on my 13" screen.
It has clearly crashed.
This happens in under 1 sec after the USB-stick is first read. After
this crash nothing happens, the USB-stick is not read. And after 10 sec,
the laptop reboots.
I have tried this stick in other machines, there it works perfectly.
(As you see, I already have have Ubuntu 10.10 installed on this
computer, but I want to do a fresh install of 11.04 Beta 2.)
