Thanks for your help, Konrad.
I did some more experiments and this turns out due to my stupid, again.

So basically the instability comes from the HW directly, it panics
once heavy load is present, either gaming or kernel compilation.
The direct cause of this HW instability is that I applied
under-voltage to my processor, which I almost forget about..
That config works fine on a native build -- it passes stress testing
from prime95.
However, the virtualization feature seems more demanding and does not
work well on that voltage setting.

After removing the under-voltage trick, the virtualized system works just fine.
So all known functionality issue about linux build have been solved.
Thank you all and apologize for wasting your time.

Thanks,
Timothy

PS: The bad news is that this instability fix does not help on the
win7 guest in anyways.
It's as broken as before.
