Hi. After recent upgrade (from 21 dec to today's src) the kernel crashes 
when starting X with

panic: pmap_remove_all: page 0xc56e07f8 is fictitious

This is an i386 box (DELL Optiplex 745) with GENERIC kernel.
Using the latest X port with the 'intel' video driver.

Relevant portions of stack trace:

#9  0xc076874c in panic (
     fmt=0xc0b3958f "pmap_remove_all: page %p is fictitious")

I still have the vmcore if someone wants to dig further.

Cheers
