>Description:
Fresh 5.3 install on a Dell Poweredge 750.  The ISIS kernel uses the same configuration as GENERIC --- I copied it over in hopes that a quick recompile might solve the problem below.  It didn't.

When 'start_vinum="YES"' is in /etc/rc.conf, FreeBSD fails to boot, with the following error message:

Fatal trap 12: page fault while in kernel mode
fault virtual address   = 0x60
fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc05e8a2f
stack pointer           = 0x10:0xe8172a1c
frame pointer           = 0x10:0xe8172a1c
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         = 643 (vinum)
trap number             = 12
panic: page fault


Removing 'start_vinum="YES"' from rc.conf permits FreeBSD to boot.  Once booted, vinum is able to start without problems.
>How-To-Repeat:
Repeats as long as vinum_start="YES" is in /etc/rc.conf.
