I'm having a problem building up a current system.
I did a minimal install from the amd64 CURRENT snapshot for 200902,
the csup'ed using the standard-supfile, then did a buildworld,
buildkernel, installkernel and reboot.
I've been trying this daily for 3-4 days, thinking that maybe their
was a temporary problem.
I only have one machine (Via VB8001) from which to do the install but
have tried the build and boot on both the VB8001 and a Gigabyte
GA-6KIEH-RH.
The kernel detects two CPUs, reports the ioapic0, then enters the
debugger with:
kernel trap 12 with interrupts disabled.
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x3c
fault code = supervisor write data, page not present
instruction pointer = 0x8:0xffffffff8056db2f
stack pointer = 0x10:0xffffffff80f81c70
frame pointer = 0x10:0xffffffff80f81ca0
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = resume, IOPL = 0
current process = 0 (swapper)
[thread pid 0 tid 100000 ]
Stopped at devclass_find_internal+0x10f: orl $0x1, 0x3c(%rax)
There's a photo of the full dump at

Any ideas what I've done wrong?
