Dear Stephen 

I'm disable msix on igb both 1 and 0 
and enable HPET in bios 

get hpet_attach panic. http://hell.ukr.net/panic/recorder_hpet.webm
so i disable hpet again and get msi_alloc and so on  http://hell.ukr.net/panic/recorder_msi.webm

So for test I'm set hw.pci.enable_msi=0 and get panic in cpp_hw_attach wich autoloaded later wile system run rc scripts

panic here - http://hell.ukr.net/panic/recorder_ccp.webm

For me it's look like some kind of resource menegment problem?
