It appears that a memory page somehow got zeroed out. This could be due a 
kernel bug or side effects of bad hardware. Begin with a kernel upgade ( or 
downgrade, or shall we say, sidegrade when you move to a kernel of the same 
version, but a different flavor of patches). If that does not help, try 
changing RAM, disk, and/or motherboard.
