fatal trap and page fault after install

[Antoine Jacoutot]

Hi !

I'm having the hardest time trying to install FreeBSD on one of my workstations.
I must say I never had this problem before.
I tried installing 5.1 then 4.8 but I always get the same error at the first
boor after install:

Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x21110
fault code = supervisor read, page not present
[bla bla bla]
current process = 0 (swapper)
interrupt mask = net tty bio cam
trap number = 12
panic: page fault

This box used to run 4.8 (updated from 4.7) perfectly well.
Any idea ?

Thanks in advance.
