I had intrepid amd64 installed when I was running 2.1.x and it ran fine. After upgrading to 2.2.0, the virtual machine aborts right after the ""grub loading, press esc to..."" screen shows up, where one would expect to see the loading bar. A quick test shows that it happens with the intrepid amd64 liveCD as well as the jaunty beta amd64 liveCD. The x86 versions of these work, as well as both amd64 and x86 of 8.04.2. The main part of the error, pulled from the log file, appears to be this: {{{ 00:00:10.206 Guest Log: BIOS: *** int 15h function AX=ec00, BX=0002 not yet supported! 00:00:10.207 Guest Log: BIOS: KBD: unsupported int 16h function 03 00:00:10.420 00:00:10.420 !!Assertion Failed!! 00:00:10.420 Expression: 00:00:10.420 Location : /home/vbox/vbox-2.2.0/src/recompiler_new/VBoxRecompiler.c(4274) cpu_abort 00:00:10.420 fatal error in recompiler cpu: triple fault }}} A full log is attached." defect closed other VirtualBox 2.2.2 fixed intrepid jaunty amd64 abort Linux other
