source code CVSup as of early this morning, system is a dual celeron, with
the following scsi controller:

ahc0: <Adaptec 2940 Ultra SCSI adapter> port 0xc800-0xc8ff mem 0xef000000-0xef000fff irq 17 at device 13.0 on pci0

after little time after rebooting, and sped up by doing a make world, I
get:

---------
Fatal trap 12: page fault while in kernel mode
cpuid = 1; lapic.id = 01000000
fault virtual address	= 0x0
fault code		= supervisor read, page not present
instruction pointer	= 0x8:0xc0131464
stack pointer		= 0x10:0xcb7a3e90
frame pointer		= 0x10:0xcb7a3ea0
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 6
current process		= 16 ( irq 17: ahc0 )
kernel: type 12 trap, code = 0

CPU1 stopping CPUs: 0x00000001... stopped
Stopped at ahc_match_scb+0x18: movl 0(%esi),%eax


and a trace from DDB shows:

ahc_match_scb()		@ +0x18
ahc_search_qinfifo	@ +0xf7
ahc_freeze_devq		@ +0x5d
ahc_handle_seqint	@ +0x135
