Whoa, you totally nailed it!
Adding nosmp DOES allow the machine to boot!
At least now we know where to start looking for the problem :)

Here's the weird part. Even though I booted with disable-qlc=true,
booting with "-v" shows numerous error message about "Unable to
install/attach driver 'qlc".

And now, another weird part: booting xen kernel, with nosmp, but
WITHOUT "disable-qlc=true", WORKS!

Is this enough, or do you still need the output of "findstack" to find
which driver is trying to attach?

As a comparison, on normal kernel (snv_99+), disable-qlc=true is
enough to allow the system to boot. So I'm guessing there's a serious
bug, most likely on qlc driver, which manifests on this particular
hardware configuration (HP blade, QLogic Corp. ISP2432-based 4Gb Fibre
Channel to PCI Express HBA (rev 02)). It works perfectly on snv_98.
