I get a kernel panic while booting Ubuntu 12.04 as a Live USB on two different computers.
One computer is custom made with Intel Processor Pentium Dual 1.8GHz with EM64T and an NVIDIA GPU card. The other is a Toshiba A200 laptop with Intel Duo Dual 2.0GHz and an ATI GPU.
I'm really good at Ubuntu. I start using it in 2010 with Ubuntu 10.04.
