>Release:        3.4-RELEASE
>Organization:
Hiarc Inc.
>Environment:
Alaris Motherboard with 28MB RAM and 486/100 IBM Blue Lightning CPU
EFAR chipset OPTi 82C822 host to PCI bridge, 1 internal IDE controller,
1 harddrive, no other cards in system
>Description:
bootstrap loader works fine. Get visual install mode, take out only
those things providing CONF (Or take out everything I don't have, either
way).  'Q' to save/boot.  Machine starts to boot, finds devices.  Just 
after npx0 at 0xf0-0xff irq 13 on motherboard it faults with:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xca57
fault code = supervisor read, page not present
instruction pointer = 0x8:0xca57
stack pointer = 0x10:0xc060ee58
frame pointer = 0x10:0xc060ee74
code segment = base 0x0, limit 0xfffff, type 0x1b
 = DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 0 ()
interrupt mask = net tty bio cam
trap number = 12
panic: page fault
Automatic reboot in 15 seconds ...
>How-To-Repeat:
ANY combination of the visual kernel config during install seems to
cause this.
>Fix:
Could NOT find a fix.  Have switched keyboards/harddrives/mem config/
taken everything out of the machine except video card (and even tried
different video cards), STILL cannot get freebsd to load
