Here is the output of dmesg | grep -i ens1371 for the 3.2 kernel boot:
 
[    7.208063] snd_ens1371 0000:04:0b.0: BAR 0: set to [io  0xdf00-0xdf3f] 
(PCI address [0xdf00-0xdf3f])
[    7.208826] snd_ens1371 0000:04:0b.0: PCI INT A -> GSI 23 (level, low) -> 
IRQ 23

Nothing very illuminating here. The intel had something about a "generic 
initialization."

I see nothing like this. The nvidia module taints but this boot is not using 
it.

This was with nouveau.

Could I try without the virtualbox by simply  blacklisting in /etc/modprob.d ?
