5.1 GEOM problems

I've just upgraded my server from 5.0-RELEASE to 5.1-RELEASE yesterday, 
using buildworld/installworld et al.  Ever since, I haven't been able to 
boot with any >= 5.0 kernel, GENERIC or custom, SMP or not (4.8 and 4.4 
work, though).  Every kernel panics with an error that looks something like 
this (this one is taken from trying to boot with GENERIC from the "kern.flp" 
floppy, from the 5.1-RELEASE CD):

Fatal trp 12: page fault while in kernel mode
cpuid =1; lapic.id = 00000000
fault virtual address = 0x5c
fault code = supervisor read
current process = 4 (g_down)
trap number = 12
panic: page fault

boot -v shows that this error happens RIGHT after it says "GEOM: new disk 
idad0", so I have a sneaking suspicion that GEOM doesn't like my raid 
controller, even though it's been working rather flawlessly ever since I've 
start using BSD.  I'm not even quite sure what GEOM is, does, or why it's 
making my kernel panic.

So I was wondering whether this was a known issue and if there was some kind 
of solution available?  Or maybe if it might just be a flagrant mistake on 
my part?  Regardless, any feedback would be greatly appreciated.
