Hello symbols from command.h aren't exported correctly. Here's a bugfix. 
It compiles with it but I haven't checked yet if compiled binary works. 
Can someone familiar with build system have a look at this?

Hi Alexander, Mark, Alex,
	Could you please help to apply the debug patch and send me back
the dmesg? Please also help to turn kernel paramemter "apic=debug".

Hi Mark,
	It seems that this regression is caused by support of multiple-MSI,
but I have no PCI card supportting multiple-MSI at hand. So may I remotely
access your system from Intel internal network?  That will definitely speed
up fix.
Thanks!
Gerry
