Ticket #6399 (closed defect: fixed)
Ubuntu host system freezes when a 64-Bit VM is launched on ASUS N90SC -UZ024V

I use Ubuntu Karmic 64-bit on an ASUS N90SC -UZ024V Notebook PC. The computer freezes immediately when "VT-x/AMD-V" is enabled and a VM is launched. (no kernel panic or something, Frozen till hard reset.)
cat /proc/cpuinfo shows me the "vmx" flag
sudo rdmsr 0x3a gives me "5"
So I think on the hardware side, everything is ok.
I can not provide a VBox.log file of a 64-Bit VM, because i did not found it. I will attach A VBox.log file of a successful 32-Bit VM run.
Windows 7 (64-bit) was pre-installed on my ASUS. With Windows as VirtualBox host, everything works. I will attach a A VBox.log file of a successful 64-Bit VM run on a Win7 host.
This problem is very disappointing for me, because I especially selected this Notebook, because its very Ubuntu-compatible and it should be able to do VT-x.
