attempted to boot 7.0 from CD, but failed
>Description:
I attempted to install 7.0 from CD (I also attempted to boot 7.0 from a livefs CD with the same result).  After the kernel was loaded, some device names 
appeared on the screen.  Then the following appeared:

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address  = 0x0
fault code             = supervisor write, page not present
instruction pointer    = 0x20:0xc06e835c
stack pointer          = 0x28:0xe2d1794c
frame pointer          = 0x28:0xe2d1797c
code segment           = base 0x0, limit 0xfffff, type 0x1b
                       = DPL 0,pres 1,def32, gran 1
processor eflags       = interrupt enabled, resume, IOPL = 0
current process        = 1 (swapper)
trap number            = 12
panic: page fault

I suppose the kernel is GENERIC.  My hardwares are:
motherboard: Asus A7V600-X
cpu: AMD Athlon XP2600+ (barton core, 32 bit)
memory:  1GB DDR
hard drive: has 4 slices: s1 (the usual unused slice), 
                          s2 (Linux boot manager, grub)
                          s3 (FreeBSD-6.2 -- I intended to install 7.0 here)
                          s4 (Linux)
2nd hard drive: has other versions of Linux and FreeBSD

>How-To-Repeat:
just boot 7.0 from CD
>Fix:
unknown
