When VirtualBox is built with a recent version of iasl, the resulting BIOS 
causes a Windows 7 VM to Blue Screen with the message "The BIOS in this system 
is not fully ACPI compliant". This is reported to the acpica project at 

Although this is NOT a VirtualBox bug, I am reporting it here so that all of you 
are aware of the problem.

A possible fix has been posted, and I hope one is available soon. The problem 
has not been reported for Windows XP, Windows 10, or any version of Linux - only 
Win 7.
