Interrupt storm detected since upgrading to 4.0 and still present in 4.0.2

Description
Since upgrading to 4.0 , my pfsense virtual machine reports interrupt storms.
I did what I could to try to minimize this:
a) disable IOAPIC b) reduce CPU to 1
but still it happens.
Worse thing is, when it happens, the CPU utilization of the virtual machine just went to 100%.
Here's a capture from pfsense's syslog. Jan 19 08:50:54 kernel: interrupt storm detected on "irq10:"; throttling interrupt source
I have noticed that one of the virtual network cards is sharing the interrupt with the acpi as well. There are plenty of free interrupts, just wonder why it is not made use of. It would be great if maybe there is a way to manually assign interrupts?

Yes it still does. But the frequency is not as severe. I am attaching a new log file for this.

Seems pfsense 2.0 rc-1 no longer shows this behaviour. FreeBSD 8 is more compatible?

Please reopen if still relevant.
Does it still happen with VBox 4.0.4?
