Running XP Mode and VirtualBox Simultaneously Causes BSOD on Windows 7 x64 RC

Ok, this is a precaution if you have installed XP Mode (Virtual Windows XP) and VirtualBox on Windows 7 x64 RC. I was testing XP Mode and I wanted to do a side by side comparison and guess what. BSOD!

My workstation is a Core i7 machine that I built myself. It’s running the latest Windows 7 x64 RC. The VirtualBox version is 2.2.2 which is the latest at the time of this writing. Further diagnostic shows that it’s probably caused by ntkrnlmp.exe. The file is part of the Windows 7 kernel.

There is no fix for the problem now, but I found that both programs still run fine. Just do not run them at the same time.

Do you experience the same problem with 32bit Windows 7 RC? Please share your experience.
