Boot failure - port-amd64 on Intel Core i7 920

[Paul Goyette <paul%whooppee.com@localhost>]

I've been happily running my Core i7 920 in a 5.99.21 kernel (sources 
dated 2009-10-24 18:29:38 UTC) with no issues.

Today, I tried updating to a 5.99.22 kernel (sources dated 2009-12-16 
14:17:30 UTC), and the kernel refuses to boot.  Very early on, it simply 
does a hard-reboot, much too soon for me to capture what it might be 
saying.  I tried to 'boot -d' into KDB, but when it hits the initial 
break-point it goes into an apparently infinite loop printing "Symbol 
not found" (stopping at the bottom of every pageful of output!) and 
never gets to a prompt.

Here's the 'cpuctl identify' from the Core i7:

cpu0: Intel Core i7 (Nehalem) (686-class), 2672.86 MHz, id 0x106a5

cpu0: Cluster/Package ID 0

cpu0: SMT ID 1
cpu0: family 06 model 0a extfamily 00 extmodel 01

The dmesg from the 5.99.21 kernel is attached.

Anyone have any clue on what may have broken?  None of my other machines 
have any problem with their own kernels built from the same sources. 
(The "other" machines include various amd dual- and quad-core processors 
as well as a Intel Core-2 Quad-core Q6600.)
