vm_fault on 8GB RAM AMD-64 with 5.4-RC3 and 5.4-STABLE

I am trying to make a Tyan S4882 (K8QSPro?) motherboard with two 2.2GHz 
Opterons and 8GB RAM to work with FreeBSD.  Both the 5.4-RC3 
installation boot disk, and yesterday's 5.4-STABLE code panic.  The 
system works fine with 4GB of RAM (it can run make buildworld).

The installed kernel panics after the "Starting sshd." message with the 
following message:

panic: vm_fault: fault on nofault entry, addr: ffffffffa9ac58000
cpuid = 1
boot() called on cpu#0
Uptime: 38s
Cannot dump. No dump device defined.
iir0: Flushing all Host Drives. Please wait ... kernel trap 12 with 
interrupts disabled

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x48
fault code = supervisor read, page not present
instruction pointer = 0x0:0xffffffff802aa243

(I copied the above from a blury photograph, so I may have mixed some 0s 
and 8s).  The instruction at the IP appears to be part of 
turnstile_wait, though  I can't see why the specific instruction could 
create a fault, so I could well be wrong here.

0xffffffff802aa040 <turnstile_wait+32>: mov    %rsi,%rax
0xffffffff802aa043 <turnstile_wait+35>: shr    $0x8,%rax
0xffffffff802aa047 <turnstile_wait+39>: and    $0x7f,%eax

I am attaching the output from dmesg; any pointers, help, ideas will be
